Svpply is a neat service that, in essence, allowed people to track and share items they wanted. In essence, it is a wishlist service that works across all sites, and captures the price and the image of the item you want.
Svpply is shutting down, but gladly they are allowing users to download their data -- in essence, all the info they stored in the Svpply site. I still wanted the data accessible on the web, and this turned out to be a near trivial project to write in python.
Limits: You can only upload 150 pictures a day to Tumblr. This may mean you need to break you
