Google Plus

Google+ is a new Friending Network site released by Google. It started as a closed beta on June 28, 2011, and went public to everyone 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, Live Journal, 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.

Google+ has examples of:

 * Call a Rabbit a Smeerp:
 * Friend lists = "Circles"
 * Adding people = "Circling"
 * Liking / Favoriting a post or comment = "+1" (Although the term's been around for a while, Google chose to adapt this as the name of the "like" feature.)
 * Voice and video chat = "Hangout"
 * Mobile messaging = "Huddle" (Although it was renamed to the more conventional "Messaging" in September 2011)
 * I Know Your True Name: Google+ requires that users go by their real names online, with suspected violators having their accounts terminated. This was later relaxed to a 4-day grace period. Regardless, the forcing of users to go by their real names has caused quite the controversy amongst those concerned for their privacy.
 * Meaningful Name: Google+ profiles are designed after profiles on Google Profiles, making G+ essentially an enhanced version of Profiles and hence its name.
