I agree with what you said about people coming and goes.
I was thinking of making a list of categories that people fall into.
For example, this forum helped me, so I don't want to ctb at the moment,
but I stay, because I like the people who come here (mostly), and
I try to help when I can (to ctb or not to ctb).
I think most people who came here early on, were Reddit transplants.
