I’ve had this idea of a larger trading economy based on boardgamegeeks “math trades.” You could list an inventory of good used items you’d like to get rid of and then you can select other people’s items that you would like to receive in exchange. Then the trading software kicks in and tells you who to send your item to and you receive an item from someone else.
This works for boardgames on a smaller scale, but on a larger scale it lacks a trust system.
A website like ebay would be required to handle the amount of inventory and user rating system. Government id and a chargeback system for disputes would probably be required to help mitigate misrepresentations.
I honestly don’t think such a service could be free, but it could work well in other niches than just board games and it would be nice to be able to trade between niches like a car starter in exchange for a blender.
I think it could be federated as well, with different instances being ran for different types of things.
We could call it “freebay”
I suppose the site operator would charge a listing fee. This would prevent people from flooding the site with too many items or a bunch of fakes.
