We’ve received confirmation from AOL that the company has acquired Socialthing!, a lifestreaming service that competes with FriendFeed. We originally reported the deal on August 1.

AOL says that the Socialthing! team will report to SVP of AOL and GM of People Networks David Liu, and will be incorporated into its People Networks division. Socialthing’s lifestreaming will be integrated into a number of AOL’s community properties, including its social network Bebo and AIM, its popular chat service.

The acquisition comes during a tough time for AOL, which has recently been forced to institute a number of budget cuts. Despite its setbacks, AOL is still keen on keeping its valuable social properties healthy, and likely saw Socialthing! as a relatively cheap investment (the aquistion price was not released, but it was probably fairly small).

Socialthing launched only five months ago in private beta. Unlike most social news aggregators, the site employs a smart algorithm that can figure out who you’re friends with, so you don’t have to explicitly define a friends list for each service.

AOL is getting into the lifestreaming business. Like Friendfeed or Facebook’s News feeds, it recently launched AIM BuddyUpdates, which lets AIM users keep up with what their instant-messaging buddies are doing on social services such as Twitter, Flickr, YouTube, and Digg. To beef up its lifestreaming capabilities, we have been able to confirm that it has also bought Socialthing!, a FriendFeed competitor that is still in private beta.

We don’t know the price, but it was likely a small purchase. Socialthing! came out of Colorado-based incubator TechStars. Once you sign up to track friends activities on Socialthing!, it keeps automatically adding new friends for the services you choose to monitor. (See our review).

Despite all the turmoil and uncertainty about its future, AOL is trying to keep up with the times. It is embracing feeds, lifestreaming and even playing nice with other IM services such as Meebo and eBuddy. Maybe it is finally realizing that there is a bigger world out there than AOL.

Update: Head over to InviteShare to help others get into Socialthing! Each user is given 10 invites to hand out.

There are a bazillion social network aggregators out there (Mike attempted to round up some of the most notable ones here). FriendFeed is the most visible of them all for two main reasons: it was founded a group of ex-Googlers and, as a consequence, benefits from a clean and easy-to-use design.

But FriendFeed’s going to have some serious competition from a TechStars startup called Socialthing!, which makes it even easier to get an overview of what your friends are doing on the web.

Socialthing! officially goes into private beta today and will let in the first 1,000 TechCrunch readers who use the invitation code “TechCrunch” to sign up (you’ll probably have to wait a few days to get your account, however). The service primarily differs from FriendFeed in the way it determines which of your friends to track. While FriendFeed actually requires users to create their own list of friends on FriendFeed, Socialthing! realizes you probably don’t want to create yet another list of your friends. So instead of asking you to do more work, it automatically detects who your friends are on the social services to which you belong.

The distinction may sound inconsequential but Socialthing!’s method actually makes things a lot easier, both for initial set up and for longer term maintenance. When you sign up for Socialthing!, you only have to provide it with your credentials to sites like Facebook and Pownce. And as time goes by, you don’t have to worry about setting up new friends on the service because it will automatically know that you’ve become friends with people elsewhere. In contrast, FriendFeed requires you to both explicitly designate friends during the initial configuration (either one-by-one or through Facebook/Gmail importing) and manually add new friends over time.

Another benefit Socialthing! has over FriendFeed is its focus on allowing users to send data back to social services (if you want to respond to someone’s tweet, for example, you can do so directly from Socialthing!). On the other hand, FriendFeed is all about reading data from services but not about writing it back.

While FriendFeed generally takes more effort, its approach does have unique advantages. You can follow friends of friends on FriendFeed and see updates from services that you don’t personally use, all because FriendFeed users have more independently-defined presences. FriendFeed also supports a wider range of services than Socialthing! (28 vs. 11, although Facebook updates are noticeably lacking from FriendFeed). Time, however, should narrow the gap.

In the end, whether FriendFeed succeeds more than Socialthing! will depend on whether people are looking for another community or just a way to easily track their existing ones. I suspect the latter will be the case.

Y Combinator wasn’t the only incubator to demo their most recent startups today. Colorado-based TechStars also brought their startups on stage – ten of them – to give the audience a first look at what they’ve been up to all summer. Each startup gave 5% of their equity in exchange for $15,000, operational support, office space and mentoring.

Most of these companies are unlaunched and seeking additional angel funding (exceptions are noted). Here are our notes on each – and see Don Dodge for his take:

EventVue builds social networks around conferences (see confabb, an existing competitor). The idea is to let people connect before, during and after conferences in an online space, to add to the physical interaction at the conference itself. The company plans on generating revenue by charging an affiliate fee for each new registration. They are currently looking for $150k in funding.

Intense Debate – see our previous coverage. Intense Debate is a souped-up blog commenting widget that adds a lot of features for publishers and commenters alike. Currently installed on 30 blogs. Installing the plug-in on your blog (WordPress, Blogger, and TypePad) adds threading, comment analytics, bulk comment moderation across all your blogs, user reputation, and comment aggregation. They are looking for $500k in funding.

socialthing! is an ambitious project that simplifies the management of digital content (blogs, photos, music, friends, social networks and links). Users can also synchronize information from and to various social networks from their profile page. Strong viral component. Revenue from advertising. Raising $500k.

J-Squared Media has launched their “Sticky Notes” Facebook application. It has 1.7 million users after six weeks, who have sent over 4 million sticky notes. They are working on several other related Facebook applications and are cash flow positive with $30,000/month in revenue from cost per action advertising. Not seeking funding. More here.

Search-To-Phone is a mobile search service via voice. Call and leave a voicemail asking about a product or service. The request is then routed to the appropriate business to call you back with information and/or a special offer. Built on TellMe and Gold Systems technologies for voice recognition. They’ve signed a business development deal with Excell Services to provess 10 million calls. They are looking for a small capital investment and more partners before launching.

Villij is a recommendation engine that analyzes your online life (social networks, blogs, bookmarks, etc.) to find people who may have similar interests as you. Raising $500k.

MadKast has the honor of being the first TechStars startup to launch. Our previous coverage is here. They’ve made a dead simple way to increase distribution for your blog with one line of javascript or one click for Blogger and TypePad. Once the widget is installed, readers can send a blog post via email, mobile MMS, or social bookmarking networks to friends. They are raising $300k in capital.

FiltrBox is a content monitoring and filtering service for blogs, news sites and other websites.

KBLabs is developing Facebook applications and widgets. Wah! Cool was their first application, which launched four weeks ago. It now has 100k subscribers and is generating 1.5 million page views per week. Other applications include Post Secrets, Motivate Me and Track Bot. The founders are going back to college this Fall but will continue to consult and build Facebook applications. They are not looking for funding.
