If you, a private individual or company, aren’t prepared to hear your users’ concerns and deal with them, then please don’t start an online service, and especially not a social network. Even if only 10% of people are upset about something, they still matter. “You can’t please everybody” isn’t an excuse when you’re running something as infinitely personalizable as a web service. You still can’t please everybody, but you can come pretty close if you care enough.
