I've done this. It isn't really fancy or complicated. It was the first thing I built with Django (My first web app actually!). It isn't done yet, as I still have to add syntax highlighting and better Textile support. Also, I currently add posts using a script instead of a web GUI, so that could be added. Also, I suppose I could add comments, but I just don't care much for them (on the page I mean). Maybe just a link to a Disqus thread...Defiantly do it. It isn't hard, and it is a great learning experience.
