Following on from my post on Vanilla, Chyrp just squeaks by the Web 2.0 bullshit-name-meter, but seems to be a nicely engineered, extensible blogging engine.

It has a Wordpress-clone admin interface, which nicely reduces the learning curve for people interested in switching. The biggest drawback with it at the moment is that there's no way to intermix text, images and videos (they are all different "feather" types), but perhaps that reduction in complexity is a good thing.

It's already got a strong community building extensions and add-ons, which is a also an excellent sign.
