"Beta Q&A site for skeptics, rationalists, free thinkers, or anyone who questions woo and pseudoscience. Skeptics is aimed at applied skepticism -- researching specific areas of woo or pseudoscience. It is not for philosophical discussions about skepticism."
It seems like it might of interest to folks here.
For those that don't know, the Stack Exchange sites use a pretty successful Q&A format and (at least the sites I use so far) have a high signal-to-noise ratio. More info on how the Q&A system works is here.
Do it, it'll be interesting to watch :-)
I enjoy skeptics.stackexchange a bit, but only for occasional passing entertainment. It's an occasionally enjoyable exercise in on-the-spot refutation of great silliness. If that isn't your bag then you probably won't enjoy it much.
I don't actually see much crossover with LW at all.
