I've been playing with the stylesheet a bit recently. The most visible change is probably the background on the sidebar, which should show up as a light gray (on my laptop's LCD, it actually has a bluish tint). I've also set the stylesheet to just use your default sans-serif font (which probably means Verdana or some Helvetica variant), rather than the first font it could find in the long list of possibilities that was there before. (You can also choose the Serif look in some browsers, but it doesn't seem to stick so it's not very useful at present.) Of course, you can override the stylesheet rules if you like. Also, there's a printing stylesheet that most recent browsers recognize; the main thing it does is remove the sidebar when printing.
As you may also have noticed, I've simplified the TrackBack links; they're the links to the right of the Permalink icon that look like « (X), where X is the number of trackbacks to that entry. (The link is bold if X is non-zero.)
Finally, I've debated about whether or not to post a blogroll. Since I wouldn't use it myself, the value to me would be minimal; plus, I'd rather not be in a position to be accused of “playing favorites.” There are plenty of great blogs out there, and you don't need me pointing you in the right direction. (I have put some links to some services I've found useful, however; GeoURL and Janes' Blogosphere are both neat tools that I recommend heartily.)
Another brief note: I've fiddled some with the headers of the pages, so Internet Explorer should finally understand that this blog is in UTF-8 encoding. Grrr.
