Really? I've been a geek since, well, always, have a CS degree and have been working as a sysadmin and programmer since 1996. There have been women along the way, in my CS program, as coworkers, at the various startups I've worked at. Some of them have been a whole lot brighter than me. And in all that time, I've never thought "oh wow, how unusual." I just don't get it.
