I would agree about the bad header - for a web guru, you should have a tight, collected, aesthetic header design.
I would also suggest placing a screenshot of the website you are reviewing to the right of the jalepeno ratings to add a little varied color to each page.
Also, in Firefox, your on/off menus are a littel tweaky . . . not sure exactly what the deal is because I don't feel like looking at code today, but right when you highlight they bug a little bit and your AdWords double up. Could just be my machine, but either way.
