I tried to get along with the Dislike button, even used it a few times myself when I thought someone was being very rude or combative, but not so much so they deserved being reported. I started paying attention to posts that get them, and I have to say, it seems to be useless without further context. I see correct, factual posts marked with Dislike. Did someone dislike that fact? The wording of the post? The user? I see opinions marked with Dislike. Why? Was there something wrong with it? Maybe the poster didn't have all the facts? Who knows. I see threads where someone Disliked almost every post. Why would you do something like that instead of posting for yourself? So then you get a dislike and wonder "What was wrong with this? Seems reasonable/factual/etc." Maybe it's the ambiguity that bugs me. Or maybe that's it's lazy and discourages discussion. If you like a post, then there's probably not much more to say. If you dislike it, then that seems to me like something that would be nice to discuss. If you just click dislike, then no one else gets to understand your thought process. Maybe the way you look at the issue is better, but we'll never know because you clicked Dislike instead of having a discussion on a discussion forum. I don't feel real strongly about it, but I do think it generally hurts the discussion quality.
