Most blogs offer a feed for comments on their posts as well as different feeds for the posts themselves. Naturally, I subscribe to the comments feed for this web site, to instantly see when someone has added a comment.
But who else subscribes to the comments feed? I sure don't do it on any blogs; if any particular discussion is that important so I want to stay in the loop, I just make sure to re-visit the page a day later or so.
Do any of you subscribe to any comments feeds?
