What punctuation mark are you?

Thanks to Amy Storms for pointing this one out. What punctuation mark am I? Apparently, I'm a colon. Shame, I was hoping I'd be a semicolon, I like those. Anyone who knows me, does this sound like me at all? I like the "brilliant" bit :)

You Are a Colon

You are very orderly and fact driven. You aren't concerned much with theories or dreams... only what's true or untrue. You are brilliant and incredibly learned. Anything you know is well researched. You like to make lists and sort through things step by step. You aren't subject to whim or emotions. Your friends see you as a constant source of knowledge and advice. (But they are a little sick of you being right all of the time!) You excel in: Leadership positions You get along best with: The Semi-Colon
