Developing a site conducive to good conversation, in general, needs work.
It's not just the echo chamber. It's the spam, the repost/duplicates and the following discussion, the trolls, the downvoting-for-disagreeing, gaming-the-system-for-'karma', the caring-about-karma, the offtopic-but-'funny'-jokes, paid-posters, etc.
The fact that every site fails when it becomes sufficiently popular says that good conversation is hard, and harder still while maintaining anonymity - and even then, exorcising anonymity doesn't seem to have helped the quality of Youtube comments.
There are various measures like hiding comment scores or capping karma that help but there's no site out there that combines them all.
