I just noticed something...today, I received a gray point and in the comment field was a comment 'my flame'. Now, regardless of whether or not I know who it is (which won't ever be done, I'm well aware of that fact), I have no idea if they're posting positive or negative to my post.
Suggestion: take out the red/gray/green squares and put in a + or - sign or something similar to show what they picked. It's rare to get gray ones but it'd be informative nonetheless.
Just thought I'd throw in something...
