I'm in about 20, but there are only a few that are really active. I usually go to my replies first to see if there are any new responses to what I've already posted to, and then to the new posts - there are usually two pages of posts that I haven't seen yet. Not really that outrageous. I used to be in more groups, but one of them was so super active that I couldn't keep up, and I'm only interested in certain kinds of posts, so I quit, lol.
