I am out of the office this week – but my colleagues have many, many ways to get a hold of me. We use e-mail, texting, phone calls, voicemail and WebEx conferencing (to share the presenter’s computer screen over the internet). I used all of those on Tuesday, actually. Still, nothing beats being there in person. One has to see if the faces are smiling or frowning at you, and what the body languages are signalling. And when someone gets up and starts drawing an impromptu diagram on the whiteboard, that is trouble for the remote attendee.
