Welcome! I gave you a list to get started but you really should follow as many people as you come across that even marginally interest you. 

I hope you enjoy your time here and if you've got any questions, throw the hashtag #asknostr in there and you'll usually get at least a few responses. 

Don't be afraid to reach out to me either, I'll either help or point you in the right direction if I don't have the answer.
