Because they don't discover new interfaces .. great protocol is good for devs and creatives .. consumers gravitate to novelty ..that is why fashion !

yeah in the end, normies don't care about protocols and censorship.
and all this bitcoin talk wont help either
Bitcoin talk is great plus for creatives .. if you are not planning to live on social media why would you leave your network unless it is something really exciting ..visually ..or stimulating ..mentally
Interface need not be best .. or beautiful.. it just need to be different ..case in point Snap ..
Besides #nostr has no mandate on being a social app .. the goal should be to onboard creatives .. enable them with collaboration ( social ) and payment layers ..and a guarantee that they won't be deplatfomed.. it is a perfect CONTENT management system !
I've already been onboarded long ago, and even use Wavlake, for example, for my music. That and I host a podcast using it too....
