Look, guys, you have to realize that even though many frown upon the social games market, it's a niche market that's here to stay. After all, social networks are mostly entertainment media and people have been playing games even before they learned to write. Social games are dumb most of the time, a mindless way to interact with friends, but people like them. The "games" tab certainly seems compelling, however they need to be aggressive on removing spam apps. That's exactly what facebook didn't do and what zynga took advantage of to the maximum possible degree. Social app developers are almost always aggressive about exploiting user behavior and communication channels to funnel growth. If google is not vigilant about enforcing their rules correctly and tuning their algorithms to be fair to all developers, it's going to be the facebook nightmare all over again.
