I like the like.
I don’t really like the dislike, because on forums that allow dislikes, there’s generally somebody who will abuse it (by systematically disliking each and every post by a particular person) even if there’s not anything controversial in the post, and therefore doesn’t justify a dislike.
Worst place is the microsoft feedback forum. At all times there seems to be at least three dedicated microsoft disciples (who may or may not be staff) online, poised to post downvotes within minutes of anybody making the slightest criticism about an unwanted change. That’s made worse by the default option (that most readers don’t know about) to demote posts with more than 3 downvotes. So it becomes a race for at least 3 disciples who are online at the time to quickly downvote anything that criticises an unwanted change before anybody else can see the post and upvote it. Result — it’s a total waste of time posting any criticism there, because any negative comments are semi-automatically hidden from anybody that might agree and upvote the comment.
