response notification for blogs

Is there any chance we could get an option for response notification in blog posts other than our own? When I post a comment to someone else's blog post and don't make a note of it, I might as well have never commented as far as I'm aware: I never see it again, and never know whether anyone responded to me or carried my ideas forward. I think there'd likely be more blog comment activity if there was some way to keep track of when people comment after us, which is probably of some benefit to TechRepublic in fostering involvement, besides the fact of the convenience factor this would give us, the faithfully reading and commenting public.
