Suppose I want to start a list of businesses that accept BTC in my hometown. How would I do that using NIP-32? With the Decentralized Lists NIP, step 1 would be a kind 9998 event as the list header, which would include the name of the list and an optional description. Step 2 would be that anyone could contribute businesses to the list using a single kind 9999 event per business. Then step 3 would be that I use personalized trust metrics to keep spam off the list.
