You know those casual games on Facebook that you don't play but all your friends do so that your front page always is spammed silly by updates like "Andy bought a new fish!" or "Megan has got a new paint job on her farm!"? Well, everybody wants a piece of that pie these days and now rumors are that Microsoft are not only looking to hire popular Facebook developers Zynga, but they are also looking to buy Crowdstar.
Crowdstar is one of the biggest development studios of these kinds of social casual annoying Facebook games, and their Happy Aquarium is the sixth most popular (and, with that, probably the sixth most hated) game available on Facebook right now. No comments from Microsoft yet.
