After being on NOSTR for a month I find it interesting and powerful, but I don't imagine it being a real Twitter competitor.
"Competition is for losers."
-Peter Thiel
Twitter categorically defines the space. They are the monopoly. It's been adopted, first mover advantage, network effect etc...
NOSTR has to define a new category for success. I understand that it has the ability to do that, but it's not clear if it will do that...
