I now run this website on WordPress 2.01 (upgraded from 1.5.2) so even though it can be hard to spot the difference, trust me, a lot has happened to the software, with several hundred bugs now fixed. 114 bugs were fixed from 2.0 to 2.01 alone.
Seems really cool so far, the biggest difference for me right now, being a brand new WYSIWYG editor to play around with.
UPDATE: Also updated with a new theme, which is called K2. And finally also managed (after numerous tries) to make a decent header image.
