I tried to post this comment on Eric Lunt’s blog in response to this post, but for some strange reason it was deemed to have questionable content.

Microfeeds can solve the problem of many users who cannot keep track of their replies to different posts on the web. Their full potential in this respect will materialise itself if they are adopted by discussion/bulletin board and blogging systems. When discussion groups serve individual posts using microfeeds we can go back to the good old newsgroup reader days, where you can keep track of all the interesting discussions in different discussion through a single program.
