Lemme splain something to you about this whole nostr thing getting popular or not.
In general computer nerds are not cool. It just so happened that technologically society has adopted tech and computer nerds got shoved into the mainstream. Now the cool kids in school were a small group that were cool because they were cool.
A lot of you younger generations were indoctrinated that everyone is accepted into the group, cool, not cool, nerds.
And now here you are
arguing why nostr is not taking off and being adopted by every one. This is because either nostr is a small group of cool kids or not. If its cool not everyone will be in the group. This is the natural order of things.
