Initially, my activity and that of the groups I was in was way up, predictably so. Now as the dust has started to settle, I see myself/my groups returning to normalcy. I've also noticed that I've finally started to automatically replace the word chapters with groups, after all this time. I think the facebookishness of this layout has had a subliminal impact on my vocabulary. -edit- It needs to more obvious when group threads are public. It takes me a while to figure it out, especially in bigger groups with hundreds of members that I don't know.
