So I started on a re-code of my previous attempt of a blogging platform on Google App Engine. So far so good. I've managed to get adding/editing posts working properly, and I've integrated Twitter Bootstrap, the Bootstrap-WYSIHTML5 plugin, and the Google-Code-Prettify plugin. Everything is saved/retrieved dynamically from the datastore and rendered using the Jinja2 templating engine.

I think my next step is to add RSS/Atom support, but I'm finding it rather difficult to actually put that together. Does anyone here have experience with writing xml feeds?
