The Forum font looks horrible on Chrome/Windows, and the JavaScript that's making a marquee out of the <title> has got to go. @font-face is a bad idea in general unless your site is only aimed at people with wired broadband (too few designers seem to grasp the concepts of download time, maximum simultaneous HTTP requests, and data caps) and while there are fall-back fonts in your theme's CSS, only one browser is currently able to use them (and that's only in the latest update, which was last week, I think). Everybody else will wind up with a text-free page with a few scattered lines on it if there's a problem downloading the font file(s).
The site itself is good apart from that. I'm not sure how the notebook style is going to go over in the wider world; the current trend is to ditch anything that resembles objects in the physical world, derisorily (and incorrectly) calling it "skeuomorphism" and having a grand old laugh. It depends who your audience is, and you won't really know that until you have one.
