Buzz definitly needed to use Nostr because it is the underpinning of the entire architectural vision behind the product. No Nostr, no blossom, no ngit, no app interoperability, no sovereign identity...non of it.
All of it only makes sense from the paradigm that Nostr introduces, and the whole point of that paradigm is that all the other possible usecases of the protocol can tie-in to whatever it is this Buzz thing is doing, if not just from an identity andor socialgraph point of view, but potentially more.
Ergo, our entire civilization needs to be made aware of this paradigm, at least to the degree they have the intuition that when it says ''Nostr'' on the box, its works with all that other stuff that says ''Nostr'' on the box. In that regard its not ''written in Go'' its ''USB", such that you know you can connect your camera to your computer.
Whenever we get to the point that alteast to a small degree such understanding exists, the twitter thread of
@jack 's announcement wont be filled by ''why not Discord'', ''Why not slack'', because they already understand how and why that is a retarded question.
