OK, so it took me awhile, so I finally found a fun use for Daytum; follow my volume of geeky things purchased.
This will be fun for you and likely infinitely depressing for me. But fun nonetheless. 🙂
UPDATE: I also decided to use Daytum to track the volume of my toy collection, and the breakdown of which era my G.I. Joe figures came from. One of my updates made the Daytum front page. Look rightward and bask in a screenshot of what was likely two minutes of highly specialized and almost absolutely overlooked Internet fame.
