I'm a college student, and my professor uses Poll Everywhere as a way to encourage participation and take attendance. She posts polls throughout the presentation and dedicates a couple of minutes to look at the responses. Because everybody wants to get credit, a lot of responses, which show up chronologically, are one-word, basic and repetitive, whereas the more elaborate responses that take more time to write are never seen. I believe that adding a function that prevents repeating FRQ responses from being shown could be especially valuable for large groups to enable more various opinions to be expressed instead of seeing the same response over and over. After all, we already have the poll function for quantitative measurements.
