Haha, your reasons for girls being rare on web design stuff are funny and maybe even somewhat true.
The social norm is that most guys are sporty or technical, while most girls are well...girly and only think about *omgah* that really really cute guy in bio class. So...having the norm set that way means that most guys would feel inclined to go into sports, or do technical stuff, like web design, while girls go to the mall or myspace/xanga all day long (which I really wouldn't consider the equivalent of managing a website). A sad but true fact.
Of course, there are people who go outside the norms, something I think should be enouraged. I mean, how many girls are on the Medal of Honor servers? The UT servers? Like, max 3 at a time? Girls can frag too!
And uh...yeah...I'm a girl.
BTW to billybob: Are you trying to pick up girls or something by starting this thread?
