Imagine a dating site for your stuff: Joe needs a replacement water reservoir for his coffee maker; Jenny just broke her coffee maker (identical to Joe’s), but the water reservoir is just fine. But how would she know that anyone needs her reservoir? She might just throw it away. Joe might toss the old, and buy a new coffee maker. That is an awful lot of waste. Somebody should make a site that takes care of that. Then Ubokia hired me to check out their marketplace.
