Might I go against the flow, by suggesting the the new style isn't that great? It's certainly a victory for style over substance.
It's OK, but I agree that the question and title fonts (Tagged/Asked/Viewed/Latest Activity/etc) are poor. The Space Invader-scarred tabs are amusing the first time you see them, I guess.
I get the whole retro thing, but there is a reason why graphics have advanced - we all know that graphics should always come second to game-play, but after the first visit, the novel impact is lost and we are all squinting.
It just seems like we are trying to be twee and retro-cool at the expense of usability. Once the initial impact is over, we are simple left with a standard stackexchange site with awkward fonts.
It's not going to put me (or anyone else, I suspect) off the site, but since you asked the question....
design
will do.
