The issue with these solutions is that they're only really one way, if I actually want to interact with anything posted to the RSS feed I have to navigate to the main website anyway, which renders the initial reading of them in a freer way pretty pointless.

If you want to interact, the way you do that is to own your own blog where you post your “reply” and use a trackback[0] url. Then the conversation is even freer and you’re in control of your content. Don’t forget to create your own RSS feed for others.

This is another way of achieving the same end, yes. Like any such solution, it requires both author and commenter to use software supporting it, which Twitter does not.

I agree, but that is beautiful right? The choice is in user’s hand if they want to interact with content or not. If they don’t want to read the content from that publisher in future they can simply do that, rather than getting three drip mails in 2 week intervals on why I haven’t read emails sent to me by them.

Since you mention choice, then this is just an option rather than a replacement. If it's a replacement then it takes away the option to interact with content (such as commenting).

I use the RSS feed as a link stream anyway. I just open the links and I'm at the main site. If I want to post a comment, and nothing else stops me like CAPTCHA I'll do it.
