With Nostr someone can make multidimensional spreadsheets with custom views, and cells can be either local values or references to values in Nostr events, or live feeds from Nostr subscriptions, or values that change using parameterized replaceable events.
The first iteration of such a crazy idea would be to just write a stupid Excel (or Ethercalc or whatever) plugin to add a =NOSTR.EVENT() or =NOSTR.ADDR() or =NOSTR.FILTER() functions. But I failed to do that when I tried.
