Add Dislike Button

I recently came across an article I only had 12 Likes, but 181 comments, 90% of which were negative about the article.  In other words, the writer was full of BS.  I'm sure the commenters would have dislike his article, had they had that opportunity.  Instead you only have a Like button.  It would serve your audience well if the articles were more peer reviewed and you displayed the Likes and Dislikes just like YouTube does.  Then people could have an understanding of the validity of the article.  Thank you, Don C.
