Along with a see results button, I think it would be cool if you could see the age ranges of the people that vote in the polls.
Perhaps the blue and pink could be split into multiple shades, with the darkest being the oldest and the palest being the under 18s, and the other age ranges in the middle respectively. If you don't want it, you could just toggle it on or off when you are making the poll :D
So, what do you guys think? Do you have any better ideas than mine? If you do, tell me!
