Poll Everywhere that I just learned about this week, word clouds. The word cloud feature has been there for a while, but now it integrates with Wordle, Tagxedo, and Tagul. To use this feature just create an open-ended response poll as you normally would. Then in your administrative panel select "word cloud" on the right hand side of the screen. From there you will be given the option to pick your favorite word cloud service.
For folks not familiar with Poll Everywhere, it is a service that allows you to collect responses from an audience via text messaging. The free plan for K-12 educators provides selection of features and quantity of responses that is adequate for almost any classroom. Watch the video below to learn more about Poll Everywhere.

Applications for Education
Poll Everywhere provides an excellent service for collecting instant anonymous feedback from students. You could use it to quickly assess a class's prior knowledge on a topic. I've also seen it used by teachers to collect feedback about the length of time it took students to finish a homework assignment.
The new word cloud options in Poll Everywhere could make it possible for everyone in the room to quickly see the most and least common responses to an open-ended question.
