When dealing with cyberspace, there are always 3 elements. First, there is an interface. This is a web browser, app, etc and the hardware it runs on. Then there is the avatar. This is the identity that the user is controlling through the interface. Finally there is the digital space itself. On Amazon, the interface is a browser or app, the avatar is the user account or guest profile, and the digital space is the online store and media gallery. On twitter, the interface is the same, the avatar is the account, and the digital space is the Twitter cesspool.

In nearly all of cyberspace, two or even all of these elements are owned by a single company, usually the space and avatar. The spaces are separate and disconnected, and users have no true control over their avatar except that which is permitted. Except for one. Within the nostr system, the interface is a client, like Primal or Damus, the avatar is wholly owned and controlled, and while the space has private and public "land", it has no owner nor can have one. All other platforms could be adapted to Nostr, and work effectively the same, but the spaces would be truly connected.

Now the question is how to simplify that for the layman.
