I guess I missed the snit/purge. I miss so much stuff...
Posters coming and going is part of the inevitable friction. This site has seen times that provided a few "opus" posts each week.
The mass separation that I had in mind involved the formation of a website, "WideAwakes." IIRC, the friction point was Rudy Giuliani.
Happy to read your report that PhiKapMom is still posting here. And, FWIW, from what I read into her personality from her posting style, I would not expect any sort of "snit" departure from her.
