Freecycle is completely awesome. I have to control myself because stuff comes up and I go, ohhhh that's neat, but do I really NEED it.
We have three groups locally, and the Seattle group alone has well over 3000 members, so it is busy. I would estimate that I have given away probably five or six "garbage cans" full that would have otherwise ended up in a landfill, things like a big bag of ragged t-shirts that a shop teacher took for shop rags for his auto class, plus some furniture that I didn't need anymore. I HIGHLY recommend it. Get rid of your junk and save the environment at the same time.
