But that ruins the idea of a Circle. If I can join into a circle, the entire idea of a circle as it relates to privacy becomes ambiguous and you lose the clear distinction that probably already isn't terribly clear among more novice users.
There's a way to fix this, but it's not via public circles. There are lots of good ideas out there about how to use tagging, filtering, sparks or combinations of the three to provide a subreddit-esque layer on top of Google+ that would enable more content and options for users while still allowing my Mom to safely post her pictures to her Family circle without worrying about "Public circles".
