Transsexualism seems way overrepresented in geeky circles: off the top of my head, I could think of seven MtF and two FtM transsexuals within my circle of acquaintances, and there might be a few that I'm forgetting. LW definitely matches the definition of a "geeky community", so assuming a relatively high base rate would have been reasonable to me, based on my experience.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
