I've installed MT 3.1 onto the system and I'm wondering if it's not quite ready for primetime. When I first loaded it up, the first thing I noticed was the comment system was out of whack. And I'm talking not even displaying right in the site menu. A few CSS fixes later, that appears to be working. However, one of the sites no longer builds properly. I guess I'll see if it works over the next few days. I'm really interested in the date posting capabilities.
