Just a quick note to all you Firefox users out there (yeah, yeah, I recently dropped Safari, so sue me. I've gone extension-crazy), I've been playing around with Stylish, a rockin' extension to Firefox which lets you apply your own css to any site, thus enabling you to make the web look like you want it to, or to fix stuff that bugs you about certain sites. For the non-coders, on their site, userstyles.org, you can find plenty of pre-written styles for specific sites such as digg, del.icio.us, myspace (thank science), &tc.
As an example, look at what I've done to my del.icio.us user page, using the 'Del.icio.us reorganized' site style by Eyal Shahar. Much better.
