Wow! Martin wrote up a howto for installing PyBlosxom on Debian for multiple people.
There's a series of things here I don't really know about (e.g. what kinds of things should go in /srv?). At some point, I'd like to fix PyBlosxom so it's more "standard" in terms of installation and configuration for web applications.
Here's the link for configs/pyblosxom which walks through installing a single software installation on Debian for multiple people.
