It's obviously still pretty rough, but I figured I'd post a link to my site as it stands right now because there's some interesting data to be seen.

All it does right now is display some histograms of total quantity of the different kinds of feed items organized over a few different time intervals. Note that the "Start Time" and "End Time" fields don't currently do anything, so all graphs include the entire database. Also, all times are in UTC/GMT.

More updates to come!
