I work as a technical writer for a small tech company. I teach a class about writing tips about once a month to all of my fellow employees. Today I used PollEverywhere to check for understanding since I was teaching a tricky concept. Seeing everyone's answers on the screen was not only great for our discussion (and reteaching), but it seemed that everyone had a LOT of fun using the tool. When I was done, everyone clapped because they had enjoyed it so much---the kind of applause that is really sincere. After the meeting, everybody raved about PollEverywhere and asked me to demonstrate how to use it. Many of them were buzzing about possible business and personal uses. It won me a ton of political points with my coworkers. So, my hat goes off to you for making a great product, PollEverywhere. You deserve the applause. :)
