Open question about comments and RSS

I’ve been wondering if there’s value in an aggregated feed of blog posts and comments. Ideally a threaded one, where the comments followed along behind the post they related to - perhaps even as children - requiring prior art or a new namespace, I suspect.

Obviously on blogs with a ton of comments that would be a hassle, but on smaller ones might facilitate conversation, no? Would it be a good idea to offer this as an alternative to the separate posts and comments feeds?
