I voted no for the dislike button.
There are times that there is too much negativity being tossed around already.
There are many who come here to post, not only to share good, happy times ... But to talk when they are feeling down, trying to get a grip and climb out of depression or have strength to continue on.
I feel that adding a dislike button will only add on more stress or depression to some who do not need more negativity. I honestly cannot think of any good that would come from having a dislike button.
Why be like every other site out there?
Be unique and a place people enjoy coming to share with other's.
