• Randomize

  OrderBy() is nice when you want a consistent & predictable ordering. This method is NOT THAT! Randomize() - Use this extension method when you want a different or random order every time! Useful when ordering a list of things for display to give each a fair chance of landing at the top or bottom on each hit. {customers, support techs, or even use as a randomizer for your lottery ;) }
