I was a huge advocate and active user of Google+. The small community here is very similar to it's levels of engagement. Google+ failed when Google decided to stop working on it. That can't happen here in the same capacity. If Vitor stops working on Amethyst another client developer can take over or be given the opportunity to shine. Because of this open nature, I believe Nostr has a greater chance than any other social competitor that's arose over the last decade.
