It's hard work breaking in new recruits. I've had a sore throat all week from trying to justify our existing code-base and customer relationships.
As hoped, the new blood is having an almost immediate positive effect. Irritations that had faded into background noise have been brought to the fore.
Someone without the tarnish of several years on the frontline can much easier see the atrocities that are committed in the name of Truth, Justice and the Extreme Way. Not that any blame should be attributed to XP - just to our slow deviation from the path of the righteous.
