A good open office can be very good, when each person gets plenty of space around them, things are generally quiet, and management isn't always wandering around

A good open office can be very good, when each person gets plenty of space around them, things are generally quiet, and management isn't always wandering around (everybody wants to check HN or reddit occasionally, but feels weird doing it when management can see). Defaulting to a setup where most people can't see each other's screens is a nice touch, and the aquarium is cool.
