I enjoy giving away stuff on freecycle on craigslist. We have met some neat people who really appreciate stuff that no longer serves us. It is so much more fun than a garage sale where you nickel and dime with people.
Cool idea. Stuff like furniture is a hassle to send, having a local group is great. It's a moderated list, which is often good. And there are also trading/selling lists for various towns on craigslist, if you would like to get a bit of money for your stuff.
