PyBlosxom, the server that runs used to run this site, supports flavours. They change your PyBlosxom site’s appearance, using templates, CSS, images, and other files, without changing its content. There’s a longer description on the PyBlosxom site.

The snarfed.org flavour is available for download. To try it out on your site, download snarfed_flavour.tar.gz and copy the contents of datadir/ and flavourdir/snarfed.flav into your PyBlosxom’s datadir and flavourdir, respectively. Then, edit config.py and add this line:

py['default_flavour'] = 'snarfed'
