The idea in and of itself is pretty cool. It's not for me, I wouldn't use it, but it's still cool and it's your blog so it should first and foremost make YOU happy. Don't worry about what I think about the superficial things like "design". That said, let me offer some constructive criticism of more important things.
The font is very small for me. I would go no smaller than 12px. I'm a young guy with 20/20 vision and it was hard for me to read.
Other than that, I think it's a cool idea. Go with it. BTW, that left angle bracket at the top of your page that you can't find; it's an extra thing in your DocType declaration in your header: `<<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Strict//EN”
At the very beginning of the doctype there should only be one angle bracket.
