I appreciate the thoughtfulness behind wanting to implement payments at the right point in the UI/UX. It’s interesting to think that where in the app the payment occurs might affect how they’re treated. From my own observations/experience, I believe that showing zaps stats on individual posts actually causes people to zap good content less. It’s as if there’s a psychological threshold where people feel a particular post has “earned enough” instead of tipping based on their own personal enjoyment. There should still be a way to zap/tip button from a  post, but it should either be a profile zap and not shown on the post, or the zap stats should be viewable only by the person who published the post. 

As for other payment options, I’m curious others’ thoughts. I believe sats are superior due to the borderless/permissionless nature of bitcoin. However, Bitcoin adoption is not widespread, and some who have it don’t spend it for various reasons. It would be easier to market content from nostr to a non-nostr audience if fiat monetization options were available (PayPal, Venmo, cashapp, credit card, Apple/Google Pay, etc). Then once people use nostr they will naturally be exposed to zaps/Bitcoin and maybe see why it is preferable. But at least in the meantime, creators could have the maximum chance to capture value for what they’re producing.
