Google AppEngine Development

There is an idea to write a little about the development for AppEngine. In my opinion, the documentation is all well and sensibly written, but it would be ideal to show the development of a more or less real application. I have two guinea pigs — one and two — I drank and drank them when I have free time. Would anyone care how they are written? (in fact, they are both open source, so the source code can be viewed anyway).

And if it was interesting - with what to start? In my opinion, it would be more interesting to write about MyTwiLinks - there is integration with Twitter, Djangov templates, and even OAuth somewhere on the side, but in FanFiction Downloader - generation of zip-files in memory (and also why I had to do it ) and work with the EPub format :-)
