No, I haven't thrown a bunch of Ajax in the mix, but I did follow the lead of many so-called Web 2.0 sites and made a couple of changes to the aesthetics.
For starters, I changed the font family from Verdana to Arial. That seems to be the way the wind is blowing these days. More significantly, I've upped the main font size from 10 point to 12. Most of you are reading this on a 17" screen or larger and just about all of you are 1024x768 or greater. You've got the room for 12 and I'm sure you'll find it an easier read once you get used to it.
If you hate the changes, don't worry. I'm bound to get bored and change it up again soon.
