So there's really no need to have a "insta"nostr or "tiktok"nostr... so for simply put extrapolation of those apps to nostr is a matter of adapting client's interface to relayed data, for so to work the stylization of social media experience
Bearish on Flare I'd to say, page has been unresponsive for some time now anyways...
But so a fair scope might be: 1) upload content to nostr:npub1nxy4qpqnld6kmpphjykvx2lqwvxmuxluddwjamm4nc29ds3elyzsm5avr7 or so, 2) pick the client that better displays the content, 3) profit... Where's the angle I'm missing?
