When I first heard about boostagrams and V4V music it seemed like a no-brainer that there ought to be a social network that allows followers to give more than just a stupid thumbs up for cool or helpful posts. Being able to return that value using Bitcoin instead of fedcoin was bonus. Not having to rely on a borrowed or rented username to do it sealed the deal for me.
Nostr is like a tiny house sitting on your own land vs a 4-bedroom apartment in someone else's building.
