In reply to Rick.

It depends what your goals are. If you are making a living off of ads then you may feel short-term hit in page views. But if you are blogging for the sake of standing out in your field, be an authority on something, or for the sake of having conversations and sharing ideas... well then the more comments the better. And we do that in spades.

Notice above I said short-term hit in page views: we've seen that in our beta testers. Sure you might miss a few returning users if you are giving them the convenience of continuing the conversation wherever they are... but the increases in your community and readership will make up for it over time.
