My nostr bootstrap method was: see who Lyn Alden, Jeff Booth etc etc are following and follow them all. Then follow more peple that seem smart and posting good content.
Now following almost 1000 nostritches from various parts of the world and my feed is never dull. I suppose nostr without the algo just works a bit differently.
I'd still like to have multiple feeds so I could focus it at certain groups tho.
Also in the search pad, try to type a name, you'll get suggestions for people on nostr and maybe you find someone you know.
