Don't personally see any reason questions such as "Has Y Combinator ever funded a startup with a GLBT founder?" matter even a tiny bit (unless there was some reason for a discussion along the lines of "Are YC people homophobic?")
Side note: I'm bi, and still don't care "where the gays are at".
I think of it as being similar to the questions about other types of minorities as startup founders. The gay community is pretty distinctive, and I'm curious to see if there's any overlap between that and the tech community. Didn't mean to offend you.
