Polldaddy is a website that allows you to create stunning surveys, polls, and quizzes in minutes. It is free to sign up and create a basic account with the obvious option to upgrade to a professional account with more advanced features for 200 dollars a year. The free option would work fine with individual classrooms because you are permitted up to 10 questions per survey and 200 surveys per month. This application could be a great asset to any classroom blog which could lead to rich discussions in and out of the classroom. One thing I really like about the polling feature is the ability to add comments. If a classroom doesn't have a blog set up the users could post comments about the survey on the Polldaddy website which links directly from the online poll, allowing for asynchronous discussion on their choices. I would likely use this site mostly for the online polls since I prefer surveymonkey.com for surveys and have a set of Smart Response clickers for quizzes.
