Yes, I use blosxom on one of my websites. My goal is to create something similar but more general in nature.
I'm tired of Content Management Systems that seem to get in the way rather than sitting in the background and doing their job. I think in trying to achieve that simplicity, I have over emphasized simplicity. My CMS will probably not be for beginners. It will be for experienced web designers who need something to make their job less tedious but not get in the way.
As I mentioned in a reply a little above this one, I'm going to split this project into two. The first project will be the lightweight CMS for serious web designers. The second will be a interface that could interact with that CMS for unexperienced web designers or users who do not know HTML.
Though this is a PHP component, it should be easy to do in Perl (of course!) and might be a useful addition to your armory:
