Nostr started off as a niche Bitcoin social protocol/platform (whatever you may call it), rode on that for quite a while, and that stereotype is still lingering because most content here is still all about Bitcoin, privacy, freedom and whatnot.
Unfortunately, the average person on X or Facebook does not care about privacy, "freedom", and particularly "Bitcoin" as a freedom money.
Humans love attention, noise and dopamine, there's none of that here. What you see here often is either an update or post about Cashu by
@calle , or you see some Bitcoin content by
@Joe Nakamoto, or Bitcoin money podcast by
@TFTC and the likes, etc .
People have a lot of sh*t going on in real life and the least they want from a social media platform is another form of extra brain work after an already stressful life reality from work or other things.
The atmosphere is too serious out here, and somewhat toxic in an un-entertaining way (cos there's toxicity across social platforms).
