Probably the right choice. Go open the YT comments for just about any video and count how many high-quality discussions are being had. I'm usually surprised to see even one well-thought out question or comment.
Bot spam on youtube is insane: I have a number of tiny view count videos (electronic test equipment teardown/repair -- no production value in the video, it's mostly intended as a reference for the next person doing a similar repair) and I regularly have to remove comments from the pornographic avatar bots. It's enough to be annoying and I am considering turning off comments even though I don't even have many videos, many views on those videos, or proximity to a money fountain.
