Nostr is a protocol built using self-owned account/identities so that it enables us to create 'decentralized' social networks and even other types of solutions.

Pretty awesome! Twitter, meh... mastodon, less meh, but still meh... Nostr... the start of something really ground breaking. Social Media has always being plagued with content moderation. They all claim they are not editors but in the end most of their workforce is dedicated towards editorial stuff. That can be good with Curation, but it can be horrible in all shades of censorship. Creators become hostages: "how long the platform ban me or my content?". Nostr puts the control back into the creator's hands. Creator owns the keys and the relays simply propagate and store content for clients to consume. Nostr is evolving real quick! a couple months ago there were only very rough clients and the protocol was also raw. But it keeps evolving at such a fast pace! Now we have multiple clients to choose from, easy relays to set up and much more.
