Recommendations for Good Blogging Software + Hosting Services?

I’ve much appreciated PowerBlogs, which we’ve been using for several years, but I’m afraid that Chris Lansdown is shutting PowerBlogs down, and we’ll have to move to some other blogging software and some other hosting company. Any suggestions, especially as to blogging software? We’re looking for reliability, easy of use, and a good feature set. We’d naturally prefer if it wasn’t very expensive, but if it costs some money to do this right, we’ll likely be happy to spend it.

If you have recommendations, positive, negative, or (especially) comparative, please post them, or e-mail me at volokh at law.ucla.edu. Many thanks!
