Welcome!

It can take a little while to get set up.

I recommend following one or two accounts and then going through their Following lists to find more accounts to follow.

The list here also has the “npub” (or searchable address) of a lot of popular accounts:

Lastly, if you tag #plebchain there will always be people to connect with and help you get started!
