At the World Economic Forum last week, I attended a small dinner that included eight Nobel Prize winners. What a privilege in itself.The question the Laureates were asked to address was "What do you see as the world's biggest challenges?" They facilitated conversations at each table, and at the end, each of them reported out.

I hadn't been offline for more than a few hours in two and a half years — and only then because I was on safari in Botswana and had no choice.Typically, the first thing I would do when I got up in the morning was to get on my laptop to check a series of sites, including Twitter, Facebook, Google Analytics, and HBR.org, to see what comments my blogs had accumulated overnight.
