Following up with my Amazon S3 bandwidth usage post, here's the daily bandwidth usage breakdown for November and December:

It's amazing how much a 50-line PHP script can cut down on S3 usage. I also took fdn's suggestions and started invalidating the local cache (local disk space is getting low).

Next step will be to merge images.tabulas.co and images.tabulas.co - currently images.tabulas still serves from S3. There are some issues right now with missing metadata on some images in the Tabulas DB - I need to run a new update script which will repopulate those entries, so I can send the proper headers down the pipe. If I can cut down Tabulas' monthly costs to $300/month, I'll be super-stoked (I was ringing up close to $600 in the middle of '08).
