I think that's probably right. I think nerd is the most common of the three though, and is sometimes considered an "umbrella" term.
Dorks seem to be the most common. In high school, there was this group of kids who would sit in the library and argue about whether vampires are better than werewolves. I just really hope that wasn't inspired by twilight.
Random: I just got in my first car "accident"... in the form of hitting a deer. I maintain there was nothing I could have done, though. It's almost like he was waiting for me, because when I say he jumped right out at me, I do not exaggerate. I was fully alert, and actually managed to not kill the deer and only get a slight dent... nevertheless, I'm sure I'll never hear the end of this.
