On: A ‘frighteningly ambitious’ way to improve email

I used to think something along Internet Mail 2000 was good. But it notifies the sender that you read it. I don't like that.

Not necessarily. The recipient systems could automatically access the URL to check for updates - ie no human in the loop. At a minimum it would notify that a system related to the recipient has checked in, but there is no evidence that a human was behind it.
