Making the rounds on Twitter, Facebook and Tumblr right now is Three Words, a super simple but mighty fun application created by teen tinkerer Mark Bao. What does it do?

Well, it tells you who you are in three words, at least according to the people that visit that Web page, that is.

When you first go to the site, you can sign up through Facebook Connect, and you’ll get a link that looks like this: http://threewords.me/robinwauters. On that page, people can describe you in – you guessed it – three words, and you can even customize your page with a personal background and avatar if you’re into that.

On Hacker News, meanwhile, Bao explains how he built the app, and asked the community what he should do now. Evidently, Bao also took to Quora, where he explained how the simple Web app went from a simple link on Facebook to a viral machine.

He says the biggest growth so far has come from Twitter and Tumblr, and also from Facebook, and that he’s built the app specifically to spread virally by incorporating a low enough barrier to entry as well as a mechanism to entice people who describe other people to make a Three Words page for themselves too.

And of course, everyone knows people love to know what other people think of them (you can do so anonymously on Three Words, by the way, so go wild on my profile if you wish).

Funnily enough, he could easily make the service even more viral, in my opinion, by simply adding some buttons so people can easily spread their custom profile link to various social networking services once they’ve signed up.

Lets hope the site stays in the air long enough for you to try it out – there are definitely some scaling issues that need to be resolved.

In an attempt to capitalize on the rise of social commerce, online auction behemoth eBay launched its Group Gifts service today, enabling users to source the power of their social networks to collectively purchase gifts.

In the case of giving big gifts on a small budget, Group Gifts enables users to “share the love (and the expense) by buying a group gift with your friends.” Getting started is really simple — I completed the process of picking out a gift, inviting my friends to help and purchasing the gift in about 20 minutes. Granted, the gift I chose was quite inexpensive, and I was able to recruit friends from various networks quickly.

We spoke with Andy Palmer, manager of buyer experience for Group Gifts, to learn a bit more about the service.

The Inspiration Behind Group Gifts

---

With the growing importance of the social graph and the booming group buying industry, it’s not a surprise that social commerce is one of the next steps toward integrating one’s social networking and buying experiences. We asked Palmer about eBay’s intentions for its newest service, and he indulged us by explaining eBay’s inspiration for and approach to developing Group Gifts:

“The inspiration came from a couple of places. First, eBay saw that people were using social websites to buy virtual gifts for their friends at a very high frequency. We thought that it made sense to take that to the next level and help people come together to buy actual gifts. Perhaps more importantly, eBay recognized that the process of group gifting as it exists in the world today can be difficult and frustrating at times, which is a shame because giving as a group is a wonderful way to give people bigger, better gifts without spending too much during these tougher economic times.

“eBay worked to create a product that would eliminate the major pain points of group gifting while leveraging unbeatable online assets to make the process even easier. By integrating eBay, PayPal and Facebook into this application, we give users an experience that employs the largest online marketplace, the safest online payment mechanism, and two of the largest social communities in the world. In doing so, eBay has created an experience that makes giving as a group easy, intuitive and fun — as it should be.”

Creating and Choosing a Group Gift

---

Creating a gift is as easy as inputting the gift recipient’s name and the occasion; but note that in order to set up a group gift, you will need to have a PayPal account so gift contributions can be collected.

If you’re hoping to get a more personalized list of gift suggestions, though, you should consider using Facebook Connect. Palmer explains, “To make more relevant gift suggestions, eBay uses information from the gift recipient’s Facebook profile to help you find their perfect gift. We match that with event information and popular gift ideas to deliver an inspirational collection of gift recommendations.”

After inputting information about the recipient, you’ll be served a list of suggestions. If you click “Get social search suggestions,” eBay pulls in the recipient’s interests from Facebook. In this case, for Meghan Peters’s Festivus gift, eBay pulled in Peters’s favorite books and music as listed on her Facebook profile. Palmer elaborated on the social search suggestions:

“Social search suggestions are gift suggestions eBay makes for your friend based on information we’ve pulled from their Facebook profile. These suggestions are what eBay considers ‘targeted inspiration.’ You’ll see a results set after clicking on one of the suggestions that will be relevant to your friend’s interest while delivering a broad spectrum of related items.

“In some cases, friends may have selected privacy settings that don’t allow outside access to their profile information. For those instances, we cannot share suggestions based on Facebook information.”

It’s interesting to note that Amazon did precisely the same thing over the summer, but its Facebook integration only shows suggested items; it doesn’t add the extra benefit of being able to make group purchases.

Besides the social search suggestions, you can also choose from categories (such as Fashionista, Nester or Lady Gadget, in this case) that “change based on both the person you’ve selected and the occasion you’ve chosen,” according to Palmer. And if you’re still not sure what gift to choose, you can check out some of the “Top Products” on eBay to see what’s popular amongst the masses. You can also access eBay Lists from the gift selection page, in case you’ve saved items that the recipient may enjoy.

Note that you can only purchase “Buy It Now” items for group giving, as the total purchase amount is known — auction items are off limits. And if your gift sells out or expires before your group raises enough money, you can replace it with a similar item or issue a refund to contributors.

Inviting Friends to Pitch In

---

Now we get to the fun part — getting friends on board to help buy an awesome gift! After choosing the gift, you’re prompted to decide how much you’ll be contributing, enter your PayPal account information and sign the virtual greeting card that is generated once the gift purchase is complete.

You can then send e-mail invites or Facebook invites privately; spread the word publicly by posting on Facebook or Twitter; or share the unique group gift URL, which directs users to the group gift page (pictured below).

From there, the only thing left to do is fulfill the goal and you’re on your way to purchasing a group gift.

We’ve covered the bulk of what you need to know to get started, but you can learn more at the official site.

What do you think of eBay’s Group Gifts service? Will you be testing it out? Let us know in the comments below.

When a service such as Facebook limits users’ creative freedom, it is inevitable that other add-on services will overcome this limitation. This is why then, we see more and more Facebook tab apps that give us more control and freedom when it comes to customizing a fan page or a personal profile.

I can’t really understand why Facebook doesn’t create an editor that lets users create a super fan page. I can only guess they don’t want to deal with it and prefer their uniform design, which may be boring but at least it is consistent and familiar. Instead, Facebook lets other people get creative and offer an array of Facebook related apps built on the API. In any case, you must know this by now: A personalized page can drive more attention and probably, more traffic to your brand.

I’ve written about this subject over, and over, and over again here at TechCrunch. In this post, I just want to give you a clear picture about the best services that are out there, by gathering all the information in one place so it’s easier to save and use as needed. (Also check out AppBistro for more Facebook tab apps and reviews).

Please note that starting today, if you own a page on Facebook, you will need to customize the page under your tab to a width of 520 pixels. The reason Facebook is changing the tab size is because they want to leave the left sidebar open when you navigate from one tab to another, which might make sense, but don’t you just feel like they are changing stuff constantly? It is really hard to follow and adjust to the new changes for everyone, which is not cool. Why would you constantly want to alienate your users?

But I digress. Here are the 12 best services for making Facebook page tabs:

Miproapps—The newest service around, Miproapps allows users to design a fan page by simply dragging & dropping elements to the center of the page. I found it to be one of the best services I’ve tried so far because it really is very easy to use, and it only took me a few minutes to create an interactive fan page.

How it works: You just need to log-in with Facebook Connect, then the service will recognize your existing pages. Pick one, and you can start working on the page: You have basic edits like choosing page colors, height, and background image. Then you can move to the advanced editor and drag widgets from the sidebar to your right, into the center of the page. It includes photo/file sharing, status updates, blogs, audio, contact form, and much more. Easily customize their settings, and your page will be ready in no time. You can always go back and change it any way you see fit. The results are quite good and look like a nice company start-page. But note, that there are lots of widgets to choose from, you might end up with a cluttered page.

Cost: 1 free page/ad supported. (more plans & prices)

Tabfusion is an ultimate tab suite for your fan page and profile. Unlike most of the services offered here, Tabfusion has an app for each tab you want to add. I believe that the Twitter tab is the most used one, and Tabfusion was the first to release this kind of tab. This is probably why it has more than 122,000 monthly active users alone. But there are many more tab apps to choose from and the integration is done in a flash.

How it works: You choose an app from here and authorize the application. You will get an-easy-to-use guide for each app after authorization.

Cost: Profile pages are free. (more plans & prices)

15 apps await you at NorthSocial, a service that can help to make your Facebook page look a lot better than it looks now. Their easy-to-use applications enable anyone to quickly create & manage a custom Facebook page. I didn’t like two things though. First is the fact that each service is individual so you can’t create a page that combines elements such as video and pictures. The other thing is that none of the plans offer you the ability to use the apps in all of your pages.

How it works: Each of the apps are installed onto a Facebook page as a new tab. Each “account” will authorize one Facebook page to install all 15 apps at one time. So you can pick which apps you want to install and they will add tabs to your selected page.

Cost: 14-day free trial. (plans & prices)

Static520 will give you the ultimate welcome page, there’s no question about it. In fact, it is almost like having a mini-site inside your Fan page. If you have a site, this might be too much for you. But if you don’t, and you have your own small business, and are looking for ways to market your brand, then Static520 is a very good place to start.

How it works: A user sign up for the service and adds their content to the massive editor. The next step is to add the static FBML app to the page you want to customize. After you set this up, all you need to do is to copy the Static520 code into the Static FBML app. Change the tab name, and you’re good to go.

Cost: Two weeks of free trial, $19/year. (fair price)

We wrote about Pagemodo recently and since then around 6,000 Pages have been installed. The editor is easy to understand and very pleasant to use. The problem however, might be the fact that Pagemodo creates a static page, which means only text and photos that are not really click-able. But I’ve heard that they are about to launch a new template that will allow you to add video as well, one that will play directly from the page. If you are not satisfied with it you could always try Miproapps for more interaction on the page.

How it works: You go to this editor, log-in with your Facebook account, and then just follow the easy-to-use steps. Watch the Demo.

Cost: One page is free. (more plans & prices)

TabSite is one of the few services that also allows you to create a Welcome tab on your personal Facebook account. So you don’t have to own a page to enjoy and utilize this feature or service.

How it works: Again, you log in through Facebook Connect, then you’ll need to sign up for the service, go through some email verification, and then you can create your own tab. The creation of the tab is done by a text editor similar to WORD, which should be really easy for users to understand. However, after trying other services, I found TabSite to be a bit old fashioned, and I really hated the picture uploader, but it might be that new users will appreciate this kind of experience. You can have one tab for each personal and fan page that you manage. You will be able to manage them all in one easy to use Content Manager area.

Cost: Free for personal profile tab. You’ll need to pay for anything else. (more plans & prices)

Involver probably has the biggest gallery of applications around. Similar to NorthSocial, you can add only one application under one tab (unless you get Involver to maintain the page for you). Anyway, you can enjoy some of the best apps for free. Apps like Twitter, Youtube, Flickr, RSS, and more, are available for download.

How it works: The implementation is easy. Click on your desired app, and Involver will find the pages you admin and will let you choose which page you want to customize. But it looks like this is only a small part of what Involver offers. I’ve seen them partner with Facebook on the Stories page, so they must have some other essential services under development that are probably worth watching out for.

Cost: Free, Pro, and Premium apps.

Static FBML is the pioneer app that lets you add advanced functionality to your Page. This application will add a box to your Page in which you can render HTML or FBML (Facebook Markup Language) for enhanced Page customization. The problem is that you’ll need to know some basic HTML code, or at least find other services to help you deal with the coding (like Flickr, for example), as mentioned in our first guide. Bottom line, this should be your choice if you have the skills for that. If not, I suggest that you try the other services. After all, they are all based on the same principles with the same end goal.

Shoptab is for anyone who wants to bring e-commerce to their Facebook page. The service will help you set up a mini-store under a shop tab on Facebook.

How it works: First, you’ll need to upload your products to the ShopTab interface (which is similar to Google Base). Add “Shop” tab to your Facebook fan page, which allows your fans to browse your products directly on Facebook. If a visitor/fan clicks on “Buy” a product at your page, it will take him to the product page at your site.

Cost: 7 days of free trial. (more plans & prices)

Clobby provides you with a way to chat with people from your own page within a simple-to-use chat tab that can be installed on any Facebook page: profile or fan. Your pages can become a platform for fans to chat, and invite more friends to join in. You’re thinking to yourself: oh, I have chat on Facebook, why would I need another one. Well, Clobby is also a collaborative Chat Room, meaning everyone can join and chat together, which is somewhat neat, somewhat annoying—your choice.

How it works: Click on this link, choose your setup page (profile or page), and simply follow the instructions.

Cost: completely free.

iLike music is perhaps the best known music tab on Facebook. The service has two apps: One for regular profiles, where everyone can list favorite music/artists, get personalized concert alerts, create and share playlists, and discover and share new music and free MP3s. The other app is for professional musicians, where they can upload their own music, and share their events, photos, videos, and blog posts.

Cost: both apps are free to use.

Unlike ‘Like’, RootMusic uses a SoundCloud connection to promote music over a musician’s fan page on Facebook. RootMusic also allows the page creator to design it the way it suits him/her. The results can lead to a great looking page that will stand apart from other pages in Facebook, which is why musicians should use it. The creation process is pretty easy, it just may take some time to add all the information about yourself (bio, gigs date, etc). All you need to do is to connect through Facebook, and RootMusic will guide you from there.

A new feature called YouTube Tracks is an uploader on the BandPage Editor where musicians can upload YouTube Tracks to their profile, which fans can then share with their friends across the web. As a musician, you can link your YouTube account to Adsense so you will start earning revenue from performance royalties every time a fan plays your track. (Demo)

Cost: Free or pay $1.99/month for pro features.

As I mentioned, on Facebook is changing the size of their pages to 520 pixels, which means that page owners (you) will need to customize pages yet again.

If you own a page on Facebook, created by yourself and it contains FBML tabs, I suggest you go and adjust it to the new customization rules. If you use one of the tools above, they will fix it themselves.
