From UtterlyBoring I picked up this link to Oregon SWAP, which looks like an interesting experiment.
SWAP is designed to promote reuse of materials in Central Oregon. It is a free and convenient way for individuals and businesses to exchange reusable or surplus products and prevent them from ending up in the dump.
Looks interesting, although the small Comic Sans font is making my eyes bleed. I also notice they seem to be running PHP for their database search. Booyah!
