From Tim Bulkeley (SansBlogue) comes news of a new blogging engine called Tumblr. Check out their blog. Tumblr (finally!) recognizes that there are different types of blog posts, and that those posts each have a common sort of form. They focus on some unique thing, but also have a lot of the same overhead. Tim quotes another source that describes Tumblr as:

The neatest thing about tumblelogs is that unlike regular blogging - which confronts you with a large, empty textarea to type your thoughts into - there are 6 distinct types of posts that have their own visual format: a "traditional" blog post, a photo, a quote, a single link, a conversational transcript, and a video.

In my 2005 SBL paper on biblioblogging, one of the things I stressed was that different "types" of posts should have different entry forms with different features that the form supported. So, one post type for 'normal' blog posts, another for bibliography entries, another for link entries ... and so forth. While I won't be using Tumblr because I just don't blog that way, it's great to see a blogging engine start to support different post types.
