I like Facebook's approach to comments (https://developers.facebook.com/docs/reference/plugins/comme...).

Pros:

- Most people are already signed-on in Fb, no friction to start commenting.

- There is a hierarchy of posts, similar to HN, reddit, etc

- Not anonymous.

Cons:

- Who owns the data? Probably Facebook.

Why is "not anonymous" a pro? Usually, you can't say what you truly think if you know that your identity is revealed, particularly if what you think is negative in nature. In Facebook people wear the same masks that they wear in real life.

Here's an interesting alternative perspective on Facebook comments, coming from one of its most prominent users, TechCrunch: http://techcrunch.com/2011/04/03/facebook-comments-epitomize...

The flipside to this is that there have been a number of articles from TC praising the new comment system, so it's not entirely negative; but I found this article to be really interesting nonetheless.

They Do let you suck down the comments it seems.
