AOL’s $850 million social network Bebo entered the lifestreaming space yesterday with the launch of a raft of new features focused on pulling in all aspects of users’ friends’ activity online even if they aren’t on Bebo, through Socialthing, the social aggregator which AOL snapped up last summer.

Adam Ostrow at Mashable puts the launch into context:

“At launch, Bebo is offering support for Facebook, MySpace, YouTube, Flickr, Twitter, and Delicious. That’s a smaller number of services than the competitors, but the company is hoping that with its unique ability to pull in activities from your disparate friends automatically, it can make up ground. Another way the company hopes to do that is by getting celebrities into lifestreaming – they tout the fact that a number of prominent artists like Miley Cyrus and All-American Rejects are already using the features.It will be interesting to see how this plays out. Socialthing hadn’t even left private beta when it was purchased by AOL, but it did seem to make social aggregation a lot easier to get excited about, since it leveraged your existing social networks and didn’t entail having to find a whole bunch of new people to follow, ala FriendFeed. There’s also AIM integration coming, wherein AIM profiles become Bebo profiles, which could lure millions of new people into the site.

AOL and Bebo have a huge audience and in many ways a better, more mainstream take on an idea that has proven successful so far with early adopters. Will it be enough to get the masses into social aggregation and prove that AOL didn’t massively overpay for Bebo? Probably only if tens of millions of people cling to it, versus the hundreds of thousands that use existing social aggregators.”

Erick Schonfeld at TechCrunch has more detail on Bebo’s new services:

“It is also introducing a visual timeline called a “Lifestory” that puts uploaded photos, events, and (soon) videos into a scrollable, chronological series of postage stamp icons at the top of members’ profile pages. Eventually, people will be able to subscribe to other Lifestories, including those from brands and bands, and embed them in their own profile pages or elsewhere. The timeline will also become the centerpiece of a Bebo iPhone app coming out soon.

The new features should all help to reinvigorate a site that has been in the doldrums lately. But Bebo’s biggest boost will come later this week when AOL migrates all of its AIM Profiles members over to Bebo on Wednesday and Thursday. This single move will more than double Bebo’s presence in the U.S., where AIM Profiles is even bigger than Bebo. According to comScore, Bebo’s unique U.S. visitors have been in decline the past few months to 5 million in January, whereas AIM Profiles has seen an upswing to 8.5 million. (See chart below). Worldwide, Bebo has 22.6 million monthly visitors.”
