I looked at the Edublog Awards to get some ideas of the best blogs. The winner of the Best Resource Sharing Blog was by Richard Byrne and is called Free Technology for Teachers. One of the resources I found is a site called Flisti.com where you can make quick polls to add into your blog (or wiki). You don't have to join the site--you just compose your poll question and Flisti will generate html code. Below is an example of a poll that took about 2 minutes to make, copy the html, and put it in this blog.
