I've upvoted, and now I'm commenting. The best of both worlds, as Hive account@unnamedsteemian points out. Notice that I've already shown that I've read this post. If I'd said "nice post" and moved on you and Ms Steemian might assume that this comment was spam, even if I read the post from end to end and thought it was the best thing since sliced bread.

A junk button, good idea. YouTube has like and dislike buttons. No matter how good the clip, a few will always dislike. Some will be incompetents who don't know what they are doing, some may have twitched in the wrong place, and some may seriously not like demonic death metal. Whatever, they get to say they think the post is garbage.

Trust me, I'm a doctor.
