The website is confusing me, can you try to explain this to me?
Nostr is an apolitical communication commons. A simple standard that defines a scalable architecture of clients and servers that can be used to spread information freely.
So it's like ActivityPub?
anyone can build on Nostr and anyone can use it.
How is it accessed, do you need to connect to IP addresses, is there a url analogy or is it all on the 'clearweb' and another layer on top.
You'd need so many people to actively be using Twitter to make a difference, that they would still stay due to the increased userbase.
