That sounds interesting. Are you thinking about a comment system build into RSS?

I am interested in potential future RSS capabilities. Would you mind a chat about that? If so, please drop me an email, see profile.

Google Reader used to have that. Then Google shut it down, probably because they wanted people to use Google+ instead.
