How does Google+ circles work?
I have all these people I don't know that keep dding me to their circles. Why do they do that? Should I be adding people to my circles? Is that a way to get more exposure?

It's a way to keep your friends and contacts organized in groups (or circles). That way, you can send messages to specific groups instead of just posting it to everybody in your "wall" like Facebook does. Maybe you want to post a "wall" message to your college friends, but you don't want your work friends to read it. Circles allow you to do that.
