Hey welcome, I'm a lazy guy so will partially paste here a note I wrote yesterday for another newcomer 

 I'd suggest you to follow people, many ppl, then check their follow list to find more interesting profiles. Follow hashtags related to your interests and include these ones on your list #plebstr #plebchain #grownostr #Nostr and of course #Bitcoin 
If you need any technical help use #asknostr... 

Have in mind that there are NO algorithms here so  it requires some kind of "proof of work"... Write notes, enable #zaps if you haven't done it yet, like and repost the notes you like and be patient, it takes a while to warm up this machinery but once it starts moving it's unstoppable :)
