Oh it’s completely different. Reddit is phpBB v2. A forum/bulletin board.
Circles is closer to kbin. You could create ad-hoc circles for your friends which worked like labels. So you could post to that circle of friends without making it public to your circle of coworkers, for instance. You could also have communities which were essentially forums/public circles. And there was the microblogging aspect too.
Which is sad because the whole circles concept was actually nice.
I was very young when I last used Google+ and remember very little. What exactly differentiates circles from subreddits as a concept?
