I'm sure that's true. I've had a very different experience though. Twitter became toxic very quickly, and I rarely heard any opinions that weren't either virtue signaling or trolling.
Within six weeks here I was finding people interested in engaging serious conversation and in building interesting things. I found more friends, more "followers" and more real human connection here.
There is a lot less "news" here. I'm not sure it's healthy anyways. We forget that people aren't news. I've ended up with some unhealthy thinking about other groups of people from watching too much news and talking to too few people.
There is a lot of Bitcoin talk here. But I don't think the coin is the point. I think it reflects a deeper culture - a culture in a true sense in that it refers to a whole lifestyle. I don't understand all of it, but I am beginning too.
I have a different perspective. I'm a Twitter refugee. I know a lot of people want Nostr to become more mainstream, but I'm afraid of that because I don't fit in any of those places and I fit here.
Anyways, I feel like Nostr has something special, so experiences may vary.
