Just so everyone knows, being honest about what you are going for helps everyone. Lying will not screw over other people but will screw over you as well.
Let me explain, if this one poll covered all the people who were going to be entering the drawing, it would make sense if everyone posted honestly what they were going for. We could all see the odds of the $500 shop credit for example. If it looks like 150 people are going for that but only 23 people are going for the $475, you have better odds of getting the $475.
The fact that people may say one thing and either be lying or just change there mind, causes problems. Also, the posting of the poll will change the way people will vote. If someone was going to go for a certain knife but noticed that it was very popular, they might change their mind to something with better odds.
In any case, I am already having a ton of fun just thinking about the strategies people will use. I might play if I remember and can be bothered to sit at my computer for an hour just waiting but I will probably end up skipping it for some reason. I don't think I have a chance in hell of winning anything but it is fun thinking about how others will play.
