Finally someone did a little research on this topic. I don't know why this topic is that big of a deal anyway. I know that when I was between the ages of 12 and 17, my attention would be all over the place. If Twitter existed back then, I probably would've used it a week, then went on to something else the rest of the cool kids were using.
The pie charts are somewhat confusing, though. Sometimes blue meant 'No', and other times it meant 'Yes'. Some consistency would've gone a long way.
