Mark talks about using good fonts for unix. However, judged from my Linux box using Mozilla, his site looked much nicer before he changed the font. It was easier to read anyway.
Screenshots of how this site and his site with the new fonts below. Click for full size.
In other news then I've been playing with a neato weblog related site the last few days... Did you know that diveintomark is one of the most popular weblogs around? From the weblogs that has been active in the last few days, movabletype seems to be the most popular weblog tool. More information later.
Update: Mark left a comment that he changed it a bit; and it looks much better now! (In my browser anyway).
