I would imagine if you looked at Facebook's signups shortly after it opened up to the public, it would probably look the same way (if you disregard the college students who were already on there at that point). Just eyeballing the people in my circles who have actually created accounts, it seems like about a 60/40 male/female split. Most of my friends and classmates are pretty tech-savvy though (well, either that or I've browbeaten them into signing up for things so many times they just went for it this time).
