This may be kind of a vague question, but exactly are the circles in Google+? I have never really understood them. I see where people have added me to circles but do not really know what that means.
When someone follows my Google+ page, when I go to follow them back one option is "Create New Circle". Should I be creating new circles for each of my pages? And if so what exactly does that circle mean or do??
I am just really lost when it comes to the whole circles thing so if anyone can help me out to explain it that would be great!
Thanks!
