AOL (NYSE: TWX) has confirmed that it has acquired social net working tool Socialthing. Terms were not disclosed. The company is going to be part of its People Networks business unit, which AOL created in May after its $850 million purchase of Bebo. News.com’s Caroline McCarthy says that SocialThing picked a good time to sell, as the expansion of Facebook’s mini-feed importer could make growth tougher for independent aggregator services like Socialthing.
