It's not only interest, it's that within larger selections brand is essential to ease choice. The point being that the Power Law tends to negate the effect of micro-transactions. If I receive 2k sats/week, now, even a 10x increase is 20k. The equivalent of $15 USD. That's less than one hours' worth of income working minimum wage, here, so that it offers little economic incentive. Now, we do have people sending us larger amounts, but those tend to be direct LN payments or on-chain, not zaps. If you aren't personally very popular and famous (this @Kendy npub's comment is indicative of wider sentiment), or part of some gated reward pool or ranking system, like @Nusa is building, then zaps offer little economic value.

And they offer negative value in a social context, such as this client. If anything, it's demoralizing and discouraging to see who is getting the most zaps. Jack, fake e-girls, scammers, engagement farmers, people who have received grants or VC money and shortly thereafter rug us all, paid memers and influencers, etc. I would really rather not know. I know plenty of people who were so grossed out by that, that they left.
