Why is there no reverse eBay? In other words, why not have a site where motivated buyers can put up notes advertising things that they really want to buy? Sure, you’d have to have the would-be buyer pay a fee so that you don’t end up cannibalizing your auction business, but it makes perfect sense — and it belongs at eBay.
The idea, by the way, comes from a recent post at the excellent Why Not? website. It is a spin-off from a fascinating 2003 book of the same name by an economist, Barry Nalebuff, and a law professor, Ian Ayres. In essence, the book suggests ways to come with creative ideas that revolve around reversing, combining, or otherwise intermixing existing good ideas.
