@grin it kind of is.
Basically, if you imagine a service type like a shared blocklist, how many instances of that service are necessary for it to be a healthy part of the fediverse?
Is one enough?
Or one per Mastodon instance?
Or one per person with an account?
Or somewhere in between?
The poll proposes one heuristic (1 << N << number of Mastodon instances) and asks whether that's good enough.
