A company based in the UK, Phones4U, is banning all email sent within the company amongst its 2500 or so employees. This is in an effort to get colleagues to get up away from their computers and interacting on a 1:1 basis more often. This is an interesting concept, but I don't know how long it will last for. I can't imaine how my life, both at work and home, would be without any email.
