I would agree BUT 
We see more positive vibes on nostr because it’s really small compared to the centralized social medias. Also, human beings can’t be happy every day by nature! Also, sometimes being more resistant due and sharing your thoughts in negative way might filter out soft people that try to please everyone and everything on internet. The more network will grow the more it will have such behavior.
