John, great article. I met you at the first Rails conference in Chicago, I've used your well written CMS, so, I'm expecting addendum's to the related RFC's and an implementation into the major MUA's with all due haste :) Seriously though, you make a great point. There is a definite distinction between "mail" and "notifications". When I went to go get my mail today, there were a bunch of actual letters, and, a bunch of postcard like notifications. Most were SPAM of course ("use our maid service!", "you need new gutters, ours are the best!", etc)... but some were legitimate reminders ("your XXX runs out in a week", "remember, we're coming by your house tomorrow"). I'm all for it, seeing that the amount of online notification-like emails are getting more and more frequent (at least in my case).
