While I've always been a fan of Movable Type (it powers this blog), I must admit that I've begun to use Wordpress more and more.
It's a very simple, Web 2.0 style template. It's widget ready. I didn't add a search form, but you can easily add one if you know even a little WP.
You can download, use and even modify under the Creative Commons Sharealike 3.0 licence. Just be sure to retain the link in the footer!
Update: Wordpress 2.5 has just been released. It's a major update. Sparsely Green is compatible with WP2.5.
