The best way I can personally evaluate Nostr is to consider the time I've spent on it versus Twitter. When I look back over the past three weeks it's more than obvious I'm spending at least 3X the time here than on Twit. Conclusion? I clearly value Nostr more.
And the best part is, Nostr is just getting started. What we're experiencing now is "early adopter" stuff. Just think what could come down the pipeline in the next couple of years!
