Well, I upgraded to WordPress 2.0. Other than some admin bells and whistles (the new visual rich editor can be helpful and annoying at the same time, thankfully you can turn it off) there is no major reason to upgrade. I’ll wait until WordPress 2.1 before I upgrade anything else.
While I was updating I also installed the latest version of Spam Karma (2.1 beta). I’m waiting until it’s out of beta to upgrade other places.
Hate the WordPress 1.5/2.0 Dashboard? Replace it with this hack from Angsuman. Loads much faster than the stock Dashboard since it doesn’t wait on useless RSS feeds to load.
