I saw the poll. Too bad it cannot be integrated into the GF post.
Yeah, but you can't prevent people from doing it over and over and over...
That is, the GF.
I do not know how many people would try to fake it.
If it was just one, and the real results were:
A: 1
B: 5
C: 2
D: 3
B should win, right? But then if that one cheated:
A: 100
B: 5
C: 2
D: 3
It would be obvious, but the cheater could be more subtle. Also, you can do more graphical stuff with programming!
But cheating is still very possible, If you have the ability to create email addresses on a domain name then you can set up a bunch of sock puppets. :/
I think you could have a lot of fun with a polling app. Let everyone vote, but for one of the contenders show an animation of their current standing. So if you are currently in first place it shows you standing on a pedestal with a first place medal, if in last place it can show a swimmer being dragged under the water by the cement blocks tied to their feet. Of course still giving the contender an option to vote.
