"nostr is a simple distributed protocol to build internet applications for social networking, communication and media.

It requires lightweight relay servers, as opposed to large federated servers like in mastodon or email, or fully p2p like scuttlebutt.

It can be used to some extent via a browser using web clients, but it's best used alongside extensions for authentication and key management"

Going back to the site, I see what you mean. Very fair criticism. The site appeals to a bunch of implicit ideals without defining its terms.
