Free Nostr idea: Conference ticket exchange.

Every Bitcoin conference, my telegram groups fill with messages about someone that has a ticket that they need to get rid of or people that are looking for tickets last minute. There really ought to be a way to aggregate these ticket offers and bids on Nostr, provided people post them here.

When you have a fungible good like that, it's important to be able to compare. Most sellers don't have enough information to price their tickets well and buyers also don't have enough information to know what they should be paying. A market solves both these problems.

Maybe it's a custom relay that collects only these kinds of offers. Perhaps there's some sort of reputation check eventually. But it's ideal for this sort of platform because clients are aggregating lots of data from a lot of sources already. Peer-to-peer price infromation would make for a really interesting application of Nostr.
