I only very rarely use it as a post processing gimmick. When a lot of things just don't work, going B&W to save an image: sometimes just works. Mostly those images that didn't have lot's of color to begin with can end really awesome. Nowadays, it's 'just a filter' anyways, and one that conveys trying to be artsy tolo much, or one that actually enhances to subject of your photo, if it's the latter, I use it, and I think, so should you.
