I'm a day late for the official Earth Day, but I was really taken with yesterday's Web pick from Very Short List. It's a site called Swaptree that lets you trade away CDs and DVDs you don't want. Instead of throwing them away, you mail them off to someone who does:

Swaptree — started by Greg Boesel and Mark Hexamer in 2004 to help people barter things — is remarkably simple to use: You sign up for an account (“join us in 8 seconds”), then rifle through your books, CDs, DVDs, and video games to find the ones with which you’re dying to part. Put them up on Swaptree (by typing in the UPC code or ISBN number), and the site instantly shows the items you can get in return — you pay only shipping, which Swaptree handily calculates for you. Wondering what to do with that dismal M. Night Shyamalan film you bought on DVD because you assumed it would be as good as The Sixth Sense? Put it up. Maybe you can acquire Fritz Lang’s M in exchange.

I like the idea of recycling those unwanted copies of "The Lake House" instead of chucking them in a landfill. I'm definitely going to try it out.
