There may be some of you that have never heard or, or used, a trace flag in your career. That's fine, though I hope you use today to a) let us know, and b) educate yourself to ensure you know how to enable a flag you need one. If nothing else, add one to a test instance, and ensure you have the skills to actually make the change.
Given the context of the editorial, perhaps more important than learning how to enable a flag would be learning how to tell if one is enabled, and if necessary, how to disable it.
