Holy crap, the upgrade from WordPress 1.5.3 to 2.0 is freaking painless. I think it took me five minutes, including the upgrade to the test copy of my site. Now that is the way software should work. Good job guys! The new editor interface kicks total ass, too.
In unrelated news I have received my first comment spam. Three of ’em, actually. I don’t know whether I should be excited or annoyed. :-) I’d say that I’ll check out the Akismet plugin that comes with WP 2 but the problem isn’t that bad (yet).
Update: It took a couple of days but the official announcement is finally out. Freaking awesome!
