Mailbucket.org

Where do people come up with ideas like this - mailbucket.org - it is an experiment in alternative methods of email management. It basically converts the email to an RSS feed thereby allowing people to subscribe to it and recieve notifications of any update. I was browsing some sites and I came across a site that had information on how you can make blogger send out feeds for comments. Right now blogger has feeds only for the site, not for the comments. Interesting, I was just thinking about that yesterday and today I came across this site - the information is quite old though. Anyway, the concept of having feeds for your email is quite fascinating. Let me try and go over this and see if it is really useful for what I'm seeking.
