I've made a few minor tweaks to the stylesheet for this blog. I'm not sitting near a windows or mac machine right now so I have no idea if things went to hell for the less capable browsers on those platforms.
I tested with the latest Geckos on linux (which should be good coverage for any platforms running Gecko-based browsers like Mozilla's Firebird browser) and I'm crossing my fingers that nothing broke horribly for those unfortunate enough to be stuck using that microsoft browser.
Also, I don't know the first thing about web design. I've just tweaked the css through trial and error until it looked the way I wanted it. If you don't like it or if you do then let me know in the comments.
