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.
The site loads very slow for me. I'm on a high speed cable connection with a decently fast computer (2.8ghz processor, 2G RAM) and things seem clunky to me. Takes a while to scroll down the page, minimize the page, etc. I'm not sure there's any way to remedy this other than removing the javascript. But that seems to me to be a large part of the site, so you may not want to remove it.
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”
“http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd”>`
At the very beginning of the doctype there should only be one angle bracket.
