You should write out descriptions of things that you would like to be able to do. You’re probably the first Brand account that is trying to manage it directly on Nostr.
So you can be the test case for others. For example, there should probably be some authoring tool that goes through layers of approval (multi author signing? Editor signing?) or a tool that at least lets multiple keys own an account. Or multiple keys are allowed to post and it shows which key posted (this is probably possible with delegation today!)
Idk everything a real brand would need. Imagine Techcrunch or McDonald’s on nostr for example
