I usually enjoy voting on simple polls and have enjoyed using Polldaddy and Zoho polls on my ning page. I haven't has as much luck pasting html poll codes on my practice wiki, but I hope zoho polls and zohowikis work together. I think polls are another way to grab attention to a topic. I like the Blogger poll feature available here, too. I haven't come up with a clear idea yet for what I could poll on but I hope I do, or someone reading this does.
