Quite welcome
They cost nothing and take about 2 minutes to set up. If I see a request for a poll, I will usually oblige.
I think they are fun but as TB says they certainly can't be relied on for accuracy. That is the reason that we have never tried to use such a poll for any opinions that would affect the community.
I consider them to be in the same value category as the various tests that we see here from time to time.
