So, Ian, you like flat files? I entirely agree; that's why I use Blosxom for my web log; I keep all blog posts as flat files under version control (using Subversion). Maybe you should consider switching from Movable Type? :-)

However I have to say the flipside of using Blosxom is that it really needs tweaking to do anything useful (and I still haven't tweaked myself a comments system) and it's possible to get so much into site tweaking that you don't actually have time to write any site content (or at least content that's not self-referential -- see for example http://www.hecker.org/blosxom/).

YArrrgggghhhh! Gnash. Yes, MT uses (or not!) MySQL. I've spent countless hours debugging MT to fix one or other of the lacking features, and I've never yet figured out where the data is hidden. So the only thing to do is to write hooks in the code where the data comes in and then kick MT in ways to trigger the easter eggs.

Blech.

But I agree. I try and keep my site tweaking to emergency stuff.
