what this looks like to the user, is that you have the abilility to click a zap button when replying. when you pay this zap and make the comment, your reply looks special (gold/highlighted). it's then considered a "zap reply".
if the payment doesn't go through it looks like a regular reply.
interesting! does the OP get to set minimums or anything like that? or should we expect torrents of 1 sat "gold" replies on notes?
yes a user-set minimum might be a good idea
Isn’t this better done with BOLT 12? That way a sender/responder could make the payment and include proof-of-payment in the same note as the comment itself. Anyone can trivially verify the proof of payment by looking at the recipient’s profile and there’s no need to have multiple notes flying around for one comment.
