Ahhhhhh, yes, melody is the new one based on movable type.

I think movable type creates fixed html pages, rather then generating pages on the fly like wordpress, so supposedly has certain advantages over wordpress as far as stability and server load goes.

But that's just an imprerssion I've gotten, I'm not sure it's a fact.

I use drupal for various mainstream things - it's been way more stable and trouble-free then wordpress.
