Purpose of "Like" button

[Arngrim_Greyashe]

Dislike buttons frequently get used just for the sake of trolling.

Likes don't mean all that much either unless you see the Like count getting into the dozens if not hundreds. Even then, it's better for others to express why they agree (or disagree) in a reply.

I disagree. I feel like a dislike button would be very well utilized here.
