Something cool that Pollerama could do, as a cross-relay service, is display the polls by demographic (relay community) and also in aggregrate (deduplicating the results by npub).

Then you can have higher-signal results for the "full" data set, than if someone just looked at the results in relay.nostr.band, or something, while everyone could still drill down by demographic. You could also display the relay.nostr.band results, of course, since it's a sort of mega-community.
