This is just a cool tool to use when collecting student responses.  Pose a question and allow students to respond.  Then, responses are displayed below the question.  If multiple students respond with the same answer, the response will display the number of people with the same response.  Just hover your mouse over the words to find out how my people came up with the same answer.

Overall, this is just a quick and informal way to check for understanding.  Answer my question about favorite web-based tool or app.  You can do so by typing your answer below or by clicking the link in the previous sentence.
