Have you ever heard of allmylifeforsale.com?
This was a kind of art project undertaken by a guy named John Freyer (Laurel knows him). What he did is pretty clear from the name of his site, and later book -- he sold nearly everything he owned, all of it on eBay.
It's a great idea, just as an experiment, but also as a fundraiser. The idea has occured to me a few times, motivated less by art or psychology than by money. If I sold nearly everything I own, there's a decent chance I could emerge debt-free, and man, that would be sweet.
What's disturbing about the idea, though, (besides the fact that it's completely unoriginal) is that I'm not sure I could do it. It scares me. And that scares me even more. I start looking around the room making exceptions... I'll have to keep at least one computer. The iPod. The frisbee signed by Phish. The sorta-rare-but-not-really-worth-anything concert posters. My vast collection of classic porn.
But boy, could I use the money. Someone want to buy something? I have nearly everything, just ask.
