A good article but much poorer than the first 4 steps.

When you refer to 'non read' activity - you do very little to point out what types of operations in the execution plan are 'non read'.

In fact apart from telling us to switch it on you don't seem to discuss the execution plan at all although my guess is we would need to look at it to understand you when you're explaining how a query was resolved.

Still a good article though.
