Um... there are a sizable amount of story-driven, politically-driven, and office humor funnies/comics Stateside. (b'-')b
Such as Dilbert, Doonesbury, Get Fuzzy, Mark Trail, Pearls Before Swine, and Get Fuzzy (I know for sure that four of those have their own websites). Even Boondocks used to be a comic, before it got it's own TV show.
EDIT: YAY! It's in Other Trivia this still won't help me hit 2500 total posts by Monday, though. :(
