Comments and other forms of p2p interaction are generally added to create a community. People don't come back to a site/store/place if they don't get a sense of community. Comments are also generally very hard to moderate by an automated system (as also shown here). I like twitch's model where the channel owner and its moderators are responsible for the kind of community they want in that channel. There are diverse kinds of community on twitch as a result. Youtube could probably incorporate some version of this for smaller-medium channels and it would work better than current cesspool.
