Banjo is currently pretty hard to install, but it provides a good set of blogging features on top of the Django stack. It is pretty well put together, and easy to edit. I think it's better than building my own blog, and I'm hoping to contribute to the project.

I tried Byteflow yesterday, and I'm impressed. Installation was easy, and it has a lot of nice features. I had a good experience working with the development community to improve the docs--they are very open to contributions. I hope to stay with this product for some time.
