Gimme Your Stuff is a fascinating blog about people from different countries swapping stuff with each other.
The lastest trade was between Japan and New Jersey, before that, England and Illinois. People just put stuff up for trade, virtually anything and everything. Okay, it's mostly candy, but there are some awesome trades like when Dave from Perth and Lisa from New York exchanged beers.
Can there be a higher calling for a website than the free and frank exchange of beer?
