All crosshairs on the same prairie dog
When I lived in Colorado, I picked up the great concept/phrase, "All crosshairs on the same prairie dog". Damon Cortesi recent blog highlights this principle. http://dcortesi.com/2006/09/07/windows-powershell/ He posted a blog about the verbosity of PowerShell and within an hour - we had 3 PowerShell people post comments. We compared notes and there were no comments when any of us responded so he must have had moderation turned on.
