This morning, I switched the theme on here, Beached, over from using meta fields to WordPress 3.0’s new custom post types. Aside from having to do a manual SQL query to covert the posts, it has worked wonderfully. This also enables me to have different permalinks for links (for example, this post is /92/wp3-custom-post-types/, while a link with the same title would be /link/wp3-custom-post-types/), and in the future, other fun stuff like separate feeds for links and posts, with one combined one. It’s definitely a very powerful feature.
