My feelings on the issue coincide with those of Ryan North. I think a lot of stereotypes, like good jokes, are rooted in some truth, but obviously can't be held as fact.
And a dork has always seemed to me like someone who's really goofy and embarrassing, but also somewhat charming. Maybe I'm just thinking too optimistically.
Edit: I fixed the spelling mistake for you.
Edit2: I voted "other" for "dork"
