Dislike Button introduced by Facebook - should CT

Tirril

Just read on BBC news that after years of requests Face Book is bringing in a 'Dislike Button' The logic being if you have a 'Like Button' then a 'Dislike' provides a fair balance. I don't use Facebook or other social media but there have been suggestions in the past that CT should have a Dislike option. However would it actually cause bad feeling amongst posters?
