Why in the hell they want to ruin Google+? I hate Facebook for two reasons:
1) It is annoying as hell to have those game requests. And if you don't block all applications, then you have to "enjoy" the constant stream of shit, when your friends request new tools in Farmville or want to share a pony.
2) Gaming becomes a sole purpose for using social networking site. Most of my friends don't bother to use Facebook for keeping touch or sharing interesting news or stories. They just spend time playing and filling their page with useless game-related crap.
I lost hope with Facebook long ago and recently joined Google+ hoping that it would be different. It seems I was wrong
