Why can't I follow everyone's comments in RSS? I subscribe, via bloglines to a hell of a lot of blogs - most of which allow comments.

What I would like is a way to subscribe to comment threads and have them delivered either into a folder in Bloglines, an email address of my choosing, or some other web-based application. If any of you lot know how to do it, you can have my second-born child, my first-born is already spoken for - why do you think I look so eternally youthful. What do you mean, I don't look youthful?

Bastards.

What would be even better would be if I could reply to comments from within Bloglines.
