But if one wants to utilize/participate in polls, they would access nostr through a client that supports them..that is the whole idea, no?

The only issue I see, specifically with Polls, is selection bias.
But you are right.
Which isn't necessarily always bad. You ask mostly client & device specific questions, so its very appropriate in those cases.
There is a long way to go before nostr polls could be sited as accurate unbiased research data and these gaps will be filled by then.
