Yes, I enjoy creating polls and answering them (as long as they're not advertising). It's a quick way to seek opinions, and analyze data without reading through 12 pages of comments, many of which are unnecessarily repetitive. It's also a tool that some people would use because of the anonymity of it. For someone who wants to give honest feedback without hurting the person's feelings (as in a "do you like this layout, color?") I can see that answering with a simple poll could be helpful.
