Email 2.0

I heard this sentence many times lately.

Joshua Baer, CEO of OtherInBox has had the idea of introduce an expiration date in every message. He wants to create a new standard for email services.

This standard could be detected by the inbox and when the expiration date has passed the message would be automatically erased.

Particularly I think it is a really good idea for some type of message like promotion coupons and it could help to create a clearer inbox.
