I’ve seen early hints of this. Posts about permaculture and horse poo, more and more about cooking and food, travel and outdoors is growing too. Lots of new languages than six months ago too.
I expect once we get a few passionate accounts in each area, that continue to share, their following will grow and Nostr diversify. I’ve noticed people even mentioning now as the best time to grow as a future top following for that content - there is definitely interest in building communities here.
