Lost productivity caused by email and other electronic interruptions

An interesting article in the New York Times "Lost in E-Mail, Tech Firms Face Self-Made Beast" describes what all people knows: that email (and the addiction to check for new emails every minute) and instant messages are causing important lost of productivity, and money.
In my personal experience I really try to delay the response when something is not important, but as I commented in my previous entry and it's described in the article, I suffering of "e-mail bankruptcy" ("getting so far behind in responding to e-mail messages that it becomes necessary to delete them all and start over") or "e-mail apnea"... you are so overwhelmed by email that you are unable to process them.

... clearly we are losing the battle against email.

Update: googling about "email bankruptcy" I have found this article "Declaring e-mail bankruptcy" reviewing important e-mail bankruptcy declarations in the pass.
