Posting that quote as the answer to why she left the whole site is a bit misleading. At the time that post was made she was referring to the change in the Chips and Chicks Thread. The thread was a long running one from OSO that you decided to bring to SOS. It was a conversational thread about what was happening in our daily life. It was a thread that RG was the glue on, she felt it was her "home". It started off on SOS much the same, but a few months ago the direction of the thread changed and it became more of a one line joke and jab thread. Posting any type of conversation started to feel out of place, like me she is not much of one line jab poster so she pulled back from posting on that thread, which was the main thread she posted on.
Why she left SOS is still confusing but it involved some issues and arguments with several of the SOS founding members and her sticking up for SpeedGirl.
