I didn't downvote, but it's a low-effort comment that doesn't really add anything to the discussion. There is no information, no argument, no widening of context, no additional perspective, nothing. It also isn't an acknowledgement-type reply like "I see" ending a discussion. In other words, it decreases signal-to-noise ratio. You can compare it to "congrats" email chains at corps. EDIT: It would be ok in a live discussion. But on a forum, not so much.
