This site (with the tagline: fuel for your digital life) purports to be the first site to combine a social network with a multi-platform app store, profiling applications for all manner of smartphones, tablet devices, eBook readers and social networks (well, Facebook and Twitter, anyway.) The site offers open reviews, chatting and member profiles along with Foursquare-style badges and profiles to reward frequent contributors. The site, enabled by cloud computing and global payment platforms, maintains its own virtual currency, "App Credits", that you can use to buy apps, ringtones, etc. The idea has merit if it can help worthy apps get noticed, but involving a middleman in app purchases (for real money) is not always comforting.
