Many of the posters here are at APS too, and it's nice sometimes to be able to ask questions and discuss topics that aren't THR material. The breadth and depth of knowledge here is astounding.
But even if it is not moderated, it does seem to be more self-policed than most unmod groups, and I think that the THR model has taken root there. I still don't see any cursing. APS is more freewheeling than The Roundtable, and may not be for everyone.
I objected when Oleg ended Roundtable, but I think APS will be better.
