I wasn't suggesting the idea already exists, I was suggesting that "clear guidelines as to what is considered to be worth repairing" in the general case is impossible and if that's a big differentiator for this new service, it won't be enough. Supporting evidence is that the_third_wave can't tell you whether your chair is worth repairing or not, they can only make a general comment that if it's got small damage worth repairing then someone might want to repair it and if it's too damaged they won't. Which is tautologically true but not helpful enough to build a broken-chair-trading site on. That is, if you put your chair on a hugely popular free-for-all site Craiglist and nobody wants it, why would you the seller want to jump through hoops to list it on a less known less established site? Anyone who wants to buy stuff to repair has heard of Craigslist and eBay and so on already, right?
