Seth reckons there are three ways to track whether people are working hard:

1. The boss can watch people in meetings;
2. The boss can watch people at their desks;
3. An honour system, where people promise to do something and then do it.

Working from home makes #1 easy and #2 pointless, but #3 is where the magic happens, and I agree.

It seems as though only the third one is a useful, long-term way to allow us to do our best work together.
