Recipe / User Stats

Create a new page showing site statistics, such as the number of users, recipes, etc; the number of recipes in each style; the most common ingredients; etc.

This should be generated periodically by using a task queue. See deferred.defer in the app engine docs, and adding a cron job to invoke it.

Take a look at:

http://philogb.github.com/jit/

Start with the App Engine deferred.defer documentation and the cron-job entry point, then review how recipes, users, styles, and ingredients are stored. Compare the proposed charting approach with Flotr2 and JIT; done means a periodically generated stats page reports the requested counts, style breakdown, and common ingredients.
