If we can create twitter circles based on URLs, or via an API, couldn't we use this as a type of Disqus/commenting platform on websites?

Or maybe an embedded twitter circle or something that is private to only those who loaded the embed? I don't know, just brainstorming but I think Twitter could definitely take on/over Disqus with something like this.

My understanding is that Twitter Circles are unidirectional single-sender multiple-recipients. Not sure how that’s compatible with website comments, which at the very least are multiple-sender, which means you need authorization/moderation mechanisms. That seems like a whole different story than Circles.
