AOL has picked up social networking site Bebo for a huge wad of cash. While we didn't really see this coming, the move makes a lot of sense. AOL's audiences tend to skew old (you know, except for the fine young folks who read AOL-owned blogs like Download Squad), while Bebo is big with the 13-24 set and has 40 million registered users.

While Bebo doesn't have the name recognition of Facebook or MySpace in the US, it's huge in the UK, Ireland, and New Zealand. And it does have a considerable US audience as well. Perhaps most importantly, regular users click on an average of 78 pages per day, showing a high level of user engagement.
