Bebo buyout by AOL!

I recently read on a CNN report that one of Irelands favourite social networks, Bebo, is to be sold to AOL in an $850m deal! Full article
It kind of confuses me as to why a company would want to sell up when it's in its prime and doing so well? The only reason that I can think of is that its owners are not very optimistic about its future, although, I really can't see the level of interest in the site taking a substantial fall any time soon, considering the huge amounts of people who use and even still join it on a daily basis.
Anyway, is bebo already on its way out? After all, they do say that the best time to sell up is when something is at its peak.
Obviously AOL have different ideas - interesting to see what will happen.
