Usability feedback re. Circles. It's a while since I read the notes on this release of Bonfire, and now I'm prompted to create a Circle it's not clear to me: what is a circle and how is different from a group?
Consider how some of this info could be made clearer in the UI:

> "A circle is simply a list of people. Bonfire comes with some default circles, like “guests” and “people I follow,”

Perhaps show existing circles in the landing page, so people can see what already exists at the same time they're prompted to create circles?

> and you can also make your own, like “friends”, “classmates”, “monster movie fans” or “people who don’t like monster movies.”

Perhaps include thes examples in the prompt to create circles. I note this prompt currently reads "create circles to organise people you follow" but I haven't yet followed anyone, so this seems a bit premature.
