Is your browser locking up when the page loads (particularly when it tries to load Haloscan)? If it is, let me know... Thanks!
UPDATE: Thank you so much for the feedback! After playing around, I realized the blogrolls were the problem. I've taken them down to speed up load time/prevent the hang-ups I was experiencing, and am playing with solutions -- I definitely don't want to get rid of them. One idea that came to mind (and I welcome your thoughts): Squidoo lenses for each blogroll. I've already got the Green Blogosphere, so why not do the same thing with the others.
