It works, but extremely few people ever notice polls and/or respond to them, mainly because their section doesn't appear on the main page to let members know there's a new one. Also, I've learned (by posting a question asking why more people don't respond to polls) that even more annoying notifications follow you when you respond to a poll, and folks ain't got no time for that.
They appear on the main page for me, right under the most current questions. It could also be that there is no way to opt out of getting a notice every time someone replies. That is the main reason I don't answer them.
