Comments are not for voting
Voting is for voting.Voting is for voting.
I've seen a lot of "+1 great answer" or slightly disguised variant "+1 I agree with [echo some part of the answer]". These comments are more noise than signal. I know, I know, we all see those answers (or questions) that really get us excited and we want to +1000 them, but we can't, so we want to comment — but we shouldn't.
If you feel the urge, consider this advice from Shog9Shog9 (and Grace NoteGrace Note) before you hit the "Add Comment" button:
A good "+1" comment is one that would be just as good without the +1 in front of it.
If your comment doesn't do anything besides echo the original post or add agreement, chuck it.
The Workplace is already especially susceptible to comment noise. Please be mindful of the cost of your comment to others, and only post comments that really add value.
