There is one crucial difference: Group Messaging BBM style...although that's then like IRC in a way sooo...So is there a fundamental difference in this and having a circle of Final Gear forum users on I duhnno, the Final Gear forums?
Exactly! Boo .edu address restriction going away!
This, for me, is the best part of G+. I don't want to share everything with everyone.I think that Google +'s privacy controls are a lot more clear than facebook. The fact that you choose who to share things with before you share due to the Circle's is a star feature.
