I think like anything, it's all a matter of how it is done. If it fits the story you are trying to tell, and you can do it effectively, go for it. I use chapters like that, or kind of similarly (not with the same zillions of copies sold net effect GRRM had... at least not yet, but I can hope, right?), and readers responded very well to it. So it can work if that's what your story needs.
