Welcome! It’s a super enjoyable place!

Profile pic - YES

Primal premium - not needed, you can get a nip-05 from lots of places including ones like nostrplebs.com and even free ones like nostr-check.com or nostrcheck.me

How do I find people to follow? - You can find people to follow based on hashtags of interest, or using other nostr apps like Nostrudel.ninja to see a global feed

What else am I missing? - highly recommend using multiple nostr clients. If you’re on iOS you could try our Damus or Nostur, android has Amethyst. You could set up a custom lighting address or run your own relay and blossom server if you really want to nerd out on all the nostr fixings 🤓

Have a great time using a truly censorship resistant social protocol!
