i've also had the idea of creating a nostr protocol for airbnb style room rental... gonna think about it some more but pretty much, my current job is going to be good preparation for me to be able to do this later on. maybe someone will even throw some funding at it so i can get more people on it. make a whole network of little sites sharing ad data and charging subscriptions for featured placement, etc. make it all pay-by-bitcoin only, zaps preferred.
