Eugene's post is too long for me to snip but it's basically what I would
have said if I was in my usual verbose mood.
Basically, I went through a similar thing on strategy wiki selecting the
"official members" of the Living People Task Force. After discussion with
Cary and Philippe, we went with three men and three women of various
strategic targeting levels and it worked out that the selection provided me
valuable input in facilitating the project. I think that, when it matters,
Wikimedians do not care about gender/race/orientation. I'm a straight male
about to turn twenty-nine, I'm definitely not in the majority of the
userbase, but I am in the target consumer usage base. Additionally, based
on my offline life experience, we absolutely value female userbase as
compared to the outside world in the US. Just my opinion there.
