The social gaming site slots in at number eight whether you go by the originally reported value of $182 million or the later, higher reported cost. Slide.com relied upon the SuperPoke! and SuperPoke! Pets Facebook applications for its business. If digitally "throwing" sheep at your Facebook friends is not your thing, Slide has been busy since joining Google. The company offers VideoInbox, a Facebook app that serves up "the five best videos every day."
Slide has come out with other apps since its purchase by Google, but interestingly not for the Android operating system. Instead, creations such as Disco, a group messaging app, are currently offered only on Apple's iOS. But given Google's recent activity, don't be shocked if Slide's apps start to come pre-loaded on Motorola models.
