In an effort to putting an end to trolling in app reviews, Google now requires users to log in to the Play store with a Google+ account. The idea is the social ID will make anonymous trolling distinctly less appealing while improving the quality of the comments. So from now on, your Google+ profile will be attached to everything you write on Play. This is like what Facebook did with its comments plug-in in an attempt to end anonymity. [Source: AllThingsD]
