There's a massive disconnect between company philosophy and company action. You find companies promoting home based working now but then organising an international conference in India, flying people in from all over the world to one place. I'm not bitter just because I wasn't invited or anything

but there is a serious point. We should video conference more, sure it's not quite the same as "pressing the flesh" but it saves money, energy and time.
Much of the technology is there already, it just needs to be trusted.
