What users wanted was a way to gauge what features are more important, so maintainers could prioritize the important issues to the community. All asked for was to be able to up vote _issues_, and be able to sort. [1]

Instead we got reactions, and it completely missed the mark. They've made it easier to be passive aggressive. Also it lingers on your post, instead of having the unconstructive comment stand on it's own. How does one respond to a down vote, make another comment saying "... hmm?"? It's weird.
