If I had more time on my hands

For your comparison: MovableType 3.1 and the recent Blogger update (no rev number I could see, but also discussed in detail here and here).

Annoying note: There does not seem to be anyway on the current Blogger home page or any other one to read the Blogger News blog archives. The Blogger Developer blog has archives but hasn’t had a new post since January 22, 2004.
