I disagree.  You say nostr is centralized but its not, its distributed with many relays. 

You say nostr is monolithic (ie: bitcoiners).  First of all its not, many people join nostr who dont care about bitcoin or are not interested in it.

Also, Bitcoiner tend to understand the concept of decentralization naturally, what better group spearhead adoption?  We already have experience with naysayers and who to waste time on or not.

nostr is doomed?  its the first distributed social media out there we ever head.

Dont have so much anxiety about nostr.  Nostr will be fine.
Worry about getting fresh air and staying healthy :)
