you can look for hashtags people use that interest to you as an affinity group, then start following that hashtag...

as you see people interact, glance at their profile and see if they seem interesting enough to follow :-)

also I found that when people leave comments under my notes, they're usually worth a follow after that too.

here's an example of the hashtag categories Im talking about...

#Jesus #Bitcoin #Bitcoiner #BTC #plebs #plebchain #hodl #BitcoinOnly #Sats #SwanBitcoin #StackSats #nostriches #grownostr #nostr #foodster #beerstr #kaizen
