Reading the comments here makes me realise that how people use the like and dislike buttons differs significantly. It reminds me of the Uber approach to rating drivers - by Uber's metrics anything less than 5 stars indicates there was a problem with the ride. There are riders who don't see it that way though, so for them, 3 stars is an average ride without problems. I rarely look at likes and dislikes. For anything large, it's full of brigading.
