There is no magic bullet, it's about finding balance. Yes, MVP is useful to show people what you're talking about. Also, it helps clarify what you're going for, helps eliminate the unnecessary. But MVP or not, nobody likes using a product that doesn't work. And you only have one chance to make a first impression (so they say). Don't release a crappy product to a large audience, but make sure not to spend tons of time on an aspect of a product without having some verification that it's something your market is interested in paying for. Both are true taken together, but it doesn't work if you get too far to one side or the other.
