Google+ is a new Friending Network site released by Google. It started as a closed beta on June 28, 2011, and went public to everyonenote on September 20, 2011.Functionally, Google+ is described as Facebook meets Twitter with a dash of Tumblr. Its most prominent feature is Circles, which are similar to friend lists on Twitter, LiveJournal, and Facebook, and is the backbone of "adding" users on Google+. You don't send a friend request to someone you want to share content with; you simply add them to one or more of your Circles, and whether they do the same with you is up to them.Circles can be used to organize groups of friends, but more importantly, when making posts, you control which Circles to make your posts visible to, on a per-post basis and which Circles can see which elements of your profile. Ideally, this allows one to add, say, coworkers, family, and classmates, yet still be able to use their account to make posts hidden from these people. If this sounds familiar, yes, Facebook has these features too, though Google+ makes these features one of their main features rather than as something in the background.Unusually for a social networking site, Google+ allows basic text formatting in posts, and, much to the joy of many users, a post-editing feature.Google+ is still not as widely used as Twitter or even Facebook; it certainly doesn't help that currently, Google+ requires users to be at least 18 years of age.TV Tropes has an outpost on Google+ here.
