As an example, here’s a poll on the PollDaddy shortcode. (It’s unofficial, in that it was created by me, rather than my WordPress.com or by PollDaddy.)
Update, one week later: I’m closing the poll. Of the 11 respondents, 9 liked the PollDaddy shortcode, and the other 2 don’t use polls, and so are unaffected by it.
The other metapoll of which I’m aware drew similar response: 8 in favor, zero against. To get to that poll/post, you can follow the first link in the comments. It may well be the the same people voted in both polls, so that fewer than 20 people actually responded overall.
