I've added a couple of extra default font names to the stylesheet and also provided an alternate stylesheet that uses serif fonts instead; hopefully this will fix the issues some have had with fonts. Also, I've added mod_gzip to this Apache installation to reduce the bandwidth requirement of the page (all the markup makes it clock in pretty big) and added a few tweaks to the generated HTML — the most important is that the last modified time of an entry is a now tooltip for the original posting time (the page is full of tooltips, in case you haven't noticed).
At some point, I should add some media stylesheets to remove the sidebar when printing. Not that you'd actually want to print this crap...
