wanting a sex-related wiki that focuses on general sexuality, or one that is angled specifically toward the sex industry.  I don't remember the link off the top of my head, but there is at least one already dedicated to sex in general.  Maybe Wiki After Dark?  Something like that. 

I do think one focused on the sex industry and some of the more, higher-end concepts associated with sexuality in general is a good idea, though.  I'd do whatever I could to support it.
