I just upgraded to the latest WordPress and I’m im…uh…pressed. The new default template is so much better than the old one, which as of today is still in use on my German blog. It’s true: Presentation matters.
The upgrade was surprisingly painless — just delete all files except wp-config.php from the server, upload the new files, run wp-admin/upgrade.php and you’re done. This page on the WordPress wiki was helpful.
As of today, I’ll stop using categories. Categorizing new posts adds too much cognitive overhead, and I didn’t see much payoff.
