What a business does is always an intersection of what the producers and the consumers want. If users want something divergent but reasonable, the answer shouldn't be, "Well, fuck you then." The right response is, "Boy, that's a a great opportunity."
As proof, look at Friendster. They owned the social networking space before Facebook even existed. But it had started out as a dating site, and the founder stubbornly insisted that it stay a dating site no matter what the users wanted. At this point they're not even a punchline; MySpace has now taken over the spot of best-known failure.
