My experience as a decentralizion enthusiast who is fairly tech savvy and was excited about the possibilities of nostr: it has boomer energy, difficult discoverability (of people, topics, and all the awesome "apps"), it puts too much on the user. No ability to protect yourself from bad actors.
Boomer energy: stuck on ideology in a faith without works kind of way. This comes from the Bitcoin mentality ie "this is the future, it's the way and the light" ...but it hasn't solved peer to peer completely after 15 years.
Discover: search and community is lacking, reliant on hashtags you have to stumble on.
User ask: average user is retarded, I'm retarded most days, just let me click around I don't want to write a program myself to do basic tasks.
Good things: vibe is friendly, builders ship a lot and fast, zaps are cool, ui is better than blue sky, minds, mastodon, urbit etc
