in the wake of Facebook introducing the 'dislike ' button - i wonder what actual service it would perform for the same reason that it wouldn't work on this forum or any forum -for the same reasons pressing a like button here doesn't imply that one dislikes those that haven't been 'liked ' -if that makes sense - disliking a post is nothing in itself without an explanation of the reasons why and in fact on here would be deemed disrepectful i'm sure , whereas one can like something without having to explain the reasons why [imo ]
