I know it will make it more like a discussion forum and less like a ‘true’ blog, but it will be cool to get an email when someone posts a comment on a post that you have commented on. No?

Say I visit someone else’s blog. I see a nice article that I would like to comment on. I put my comment, but then I even forget that I had posted a comment. If someone else responds to it, or just casually posts another comment, it would be cool to see what they have to say.

Of course, this applies only to NON-ANONYMOUS commenters ;-)
