StudioPress has released a new theme that takes advantage of WordPress 3.1 post types. They consider Tapestry a Tumblog style theme, but I see it as simply a traditional blog theme with the added plus of post types.
I’m not going to delve into what post types are right now, except to say that different kinds of posts can have different formats. A simple example is the quote post type. It doesn’t need a lot of the extra meta data that comes with a full blown post. You’ll see an example here.
I’m testing Tapestry here at www.jeffhester.net and will be experimenting with post types. Stay tuned…
