The parent Game Dev site's banner-style header reminds me of a bad 90s website with an added MySpace ad. It's distracting and wastes space. Look to the sister sites for efficient, non-distracting headers (except for gaming.stackexchange.com, of course).

It's up to you guys, but this was my first impression of the site. In my opinion, StackOverflow.com has nailed it. It's clean, space-efficient and doesn't make my eyes scream.
