Well, I had a rather long and descriptive post prepared, but now my computer decided to crash so I'm just going to have to try and remember the important parts. Pretty much I figure that if girl's thinking is like guy's in at least this way, which I have to assume since I have never been a girl, then they will do things based on what they're around most, and see people being rewarded for. For some reason it must be that less girls than guys are exposed to guitar playing, and in fact it may feed itself, because there are so few girl rockers that girls have less of a reason to become interested in the first place. Lots of guys start because of dreams of glory and fame (and ladies), and girls don't see as much of those rewards for female artists, simply because there aren't as many to see.
