Most importantly, zaps offer an alternative to advertising.

i don't believe we've seen a business here taking advantage of this though. when we do, we'll probably also see algorithms being built into clients to show content with higher zap values. ugh. i don't know if we want that.
I've been testing that out recently. Everytime I follow someone new I send them a 100 sat tip with a message 'Followed - BTC Fiend' figuring if a user sees that note attached to their tip, they might be so inclined to follow me back. I imagine this type of 'guerilla marketing' could also be used in the advertising space.
That’s a good idea
