B&W is only worthwhile if it's used to make serious and true art.
A good solid example of that would be a black and white toned image of a baby with selective coloring of an enormously giant fake abnormally garish pink flower thing strapped to it's head, ideally, soft-blurred to hell and back, and possibly faux-HDR'd with tone-mapping to within an inch of it's life, which makes it worthwhile as serious art.
All the better if that serious art image of the baby starts out with real film shot using an antique camera using only natural light, by someone who knows that digital sucks. Only someone like that can truly appreciate the awesome value of B&W photography.
