interesting, I don't remember them ever being very prominent. maybe that's just me not paying attention to the software I use :) I'm not sure if Google will experience the same thing with Circles. I think what will happen (enter speculative mode) is there will be a large group that LOVES classifying their friends like this, and they will stick with G+. Another large group will HATE it, find it extremely annoying/pointless (possibly because of only using one or two circles, like you mentioned), and maybe stick with FB. Either way, people will most likely end up with an account on both, using one actively and one passively.
