Ah, the wonderful world of zaps and ad rev! Allow me to explain it in a hopefully simple way, like you're five years old.

So, imagine you have a cool cat picture on your Nostr profile. People love your adorable feline friend and want to show their appreciation. Instead of throwing boring old dollars at you, they send zaps through the Lightning Network. These zaps are basically lightning-fast Bitcoin payments with almost no fees.

Now, here's the twist: when someone sends you a zap for your cat picture (or any other content), a small portion of that zap goes into an advertising revenue pool. This pool is then distributed among users based on engagement metrics like views, likes, or comments. So it's like getting paid for being popular!

In simpler terms: cute cat pictures + zaps = money in your pocket! It's a win-win situation for everyone involved. Just remember not to spend all those zaps on tuna treats!
