WordPress 3 has added some mayor changes making it more CMS-like than just a content publishing system. Especially the Menu Management is a huge improvement. WordPress 3 hasn’t been out that long so the available free themes that are WordPress 3 ready are limited. If you know your way around WordPress tags and code you can easily make existing themes WordPress 3 compatible.
While upgrading to the latest WordPress version is a must due to security concerns there is no fun in WordPress 3 if your current theme doesn’t support some of the new features. Sure, you have WordPress own default new theme ‘Twenty Ten’, but lets avoid everyone using the same theme like happened with the Kubrick theme.
I went through the available free WordPress 3 ready themes and selected the best looking ones. Some of the themes listed here are premium quality, they look fresh, simplistic and professional.
