I hardly consider the concept of "If you don't know what it does, don't mess with it" an advanced user concept. Maybe I'm way off on my idea of the average computer user, though--perhaps the "I already know it all, and I can fake my way out of it if I find out I don't know it all" attitude so prevalent in other areas takes root here, too. A little education might be in order here, so people aren't afraid of harmless actions and are afraid of dangerous ones.
