I've written a simple content management system called Pyplate. It's written in Python and it's powered by an SQLite3 database. Pyplate supports features like page caching, generating sitemap and rss files, SEO friendly URLs etc.
Pyplate is currently aimed at self hosted web sites, blogs, small business, and personal web sites. I've been using it myself for about a year, and I've found it easy to use and reliable.
I released the code on my new site about a week ago, and I'm looking for beta testers. Check it out at http://www.pyplate.com
, and let me know what you think. It would be great to get feedback about the site and Pyplate.
