I like this quote from Bob Metcalfe on the evils of collegiality:
Please excuse any lack of collegiality on my part. Collegiality is not high on my priority list. After decades of fighting the status quo, I am wary of collegiality. Among the pathologies of collegiality are old boy networks â€” entrenched, resourceful, and nasty defenders of the status quo.
