Business Week has a superbly well-written article on digital communications, and what happened when one of a big bank's investment bankers OD'd on his Blackberry.
"The analytically gifted investment banker had morphed into a zombie-faced thumb man, wheeling through his engorged in-box as his last activity before going to bed and his first upon waking. ...He plucked his hyperactive BlackBerry from his silk-lined pocket and proceeded to smash it on the gleaming granite countertop of his London home. ...The onetime productivity wonder has turned into a maddening time waster.
According to the article, firms like Kodak, Yahoo and Disney are using tools other than email, like Instant messaging, Wikis, RSS and blogs, in an effort to overcome the spam, time wasting and procrastination that email brings. I think that's a great idea, and work in a similar way myself. Don't think I could ever ditch email though!
