He realised that the young people he was recruiting had moved on to using social networking sites and instant messaging. When asked, they thought that only 15% of the email they received was of any use, but had to check it all for fear of missing something.
I think he's on to something here. Email has become a monster, enabling people to bombard you with rubbish that is rarely of relevance. Too often it is a replacement for action, where sending someone an email is considered a solution in itself, rather than actually fixing a problem. It is a permanent record and easily forwarded to others, so you have to watch what you say, which for people like me is a nightmare.
It will be very interesting to see what system they come up with to use instead.
