One small change I would like regards whatever magic runs the recent comments/posts widgets. I recently loaded the site on a work computer (!) that was sufficiently ancient as to not understand any of it, and the site loaded amazingly fast (excepting recent widgets, which were disabled). So I suspect that whatever magic runs it is blocking the site from rendering immediately, as it tends to take a couple seconds on my somewhat-modern-but-still-ancient laptop that runs Chrome.

Of course, I know next to nothing about dynamic webpages, so feel free to ignore this if it's completely misguided.
