Some of the game developers who embraced Google+ (GOOG) last summer are now abandoning it, thanks to the would-be Facebook (FB) rival's low usage rates. Facebook developer Wooga's Monster World game has been pulled from Google+, and more Wooga removals are on the way. Electronic Arts' (EA) Bejeweled Blitz will be pulled on Monday. Businesses also appear to be jumping ship. The way things are going, much of Google+'s value will end up revolving around its +1 button.
