Is there the possibility of the site using a similar system to some other forums were users can thank/like posts made by individuals?
Apart from the obvious this could allow some threads to become less cluttered as the post saying "+1" could simply be replaced with a click of a box.
Also it'd give a balance to arguments. During routine disgruntlements weight could be given to one side by multiply users using the function to show there support of one person or another?
Just a thought.
