Here is how it works....
First you click either Thanks or Thats Stupid:
Then you will be taken to a screen that says "Your Vote has been cast", and you can return back to the topic or whatnot. So it takes an extra second to click.
Essentially you are giving a "Like or Dislike".
After your vote you will notice a green / red bar.
That is in effect how the difference of how many people Thanked and How many people took the time to tell you "Thats Stupid". By hovering over it, you can see how many times people chose which option.
Now i know this could cause problems... so please be nice. lol
Ill leave it like this for a bit.
