Second, I am not recommending the technique outright, but rather some experimentation with it. Under the appropriate circumstances it can look very good, however I also recognize that most of my shots that look decent from shooting nightshot were in a situation where there was plenty of light around. All the nightshot served to do in these cases was to get more detail out of shadows and to be more forgiving of looking into bright light sources with the subject in the darker foreground.
In a situation where you cannot control the lighting, you have to do what you have to do to get the shot. When I was shooting weddings for a living (on film), I would use 1000 speed film for a candle light ceremony, but I wouldn't consider such a loss in quality, if I could do something to raise the light levels.
Third, I am very big on breaking mold and trying new things. Definitely know the standard cookie-cutter formulae (i.e. the way everyone has done it since one innovatior found something that worked), but then if there's something you think could be better, give it a shot. ...
I'm all for testing the limits, but the reason we light any scene like we do, is to make the lighting look natural to the camera. Cookie-cutter or not, the fact is that cameras do not "see" the way we do. If you go sit by the campfire and you let your eyes wander, you'll find that the campfire looks bright, and orange, but not too bright when you look at it. When you gaze into the woods, your eyes quickly adjust so that you can see whatever is revealed by the weak light of the fire, the moonlight, etc., and when you stare into the sky, you see stars that can only be recorded on film by tracking them in a long exposure. It is simply a fact that you cannot reconcile all of these things with a single exposure setting in your camera, so you must fake it by adding light to the dark areas and exposing for the bright areas.
I know I sound like a 90 year old, professing the merits of the old ways, but light has not changed, the human eye hasn't evolved much in the past 10,000 years, and cameras, from film cameras to the most modern HD video cameras, all fall prey to the single-focus, single-exposure per frame syndrome. Reconciling the differences between our perception and the camera's limitations is the hallmark of a great photographer.
That is not to say that you should not study the capabilities of your equipment and know how to get the most from it. All I am saying is that to achieve a natural looking shot on camera, it is necessary to give special attention to your lighting. The more context you include in your shots (i.e. wide shots) the harder it is to get it all right. If in doubt, keep your shots tight.
Rock on!
