I couldn't agree more with +Tarus Balog
on the mute, and it's one of the major problems I have with Facebook as well, Shane. Often I want to like something on Facebook, but I don't need to see a million "Congrats!" or "Cute baby" comments from folks I don't know. It seems like Google+ gets that social networking should allow various levels of socializing, depending on the person or the specific instance. The circles are cool, I think I have a basic ideea on how I'm using them, but this could change as more folks join.
