People often ask us "What's the difference between Poll Everywhere and (some other system)?" We can afford honest transparency because we're one of the better products out there.
This data was collected across 2012, and is being published in September, 2012. We don't have the resources to maintain it continuously, but we are open to corrections and your opinions about how to more fairly present the data until November, 2012.
