I spent an evening messing around with Pyblosxom. I was going to use it to restart my keyboard blog. It was supposed to a somewhat fun exercise in python, and I was also tired of the Movable Type admin interface being so slow.
After a couple hours of hacking, I decided that Pyblosxom is too much work.
And then I found out about MT4's built in fastcgi support. This artcle provides you with the config details. It's strikingly simple. You also have to turn on FastCGI for your domain using the Dreamhost Control Panel if you're on DH.
Now the admin interface is much more tolerable. Looks like I won't have to roll my own after all.
