@noodles,
Yep, pulling the ratings and histograms on a schedule sounds fine. As for the actual reviews for an app, I imagine those would be pulled in on demand and cached, for a certain time.
Possibly storing these in the DB also, along with the data for the app, with an expiration time? I'm not sure relying on something like httplib2's caching would be enough.
