I would still caution that too many "it depends" becomes "I'll do it like I want without understanding why the best practice is the best practice."  Just an observation that I've made all too often in real life.  Maybe better to phrase "normally this way but we need an exception here because..."  I occasionally use NOLOCK under very select circumstances.  But I don't proceed from there to say "it depends."  I would say NOLOCK is generally a bad idea because.....  However, in this case it's okay because …..  That's not the same as "it depends."
