I would argue that people need to stop making generic social networks. But take a look at sites like StackExchange: It is definitely a "social network", even though it doesn't have friend requests, only recently added photo uploads (and only kinda), and doesn't even have a Farmville-killer. But it's incredibly useful, highly successful, and might one day even be very profitable. Facebook started by billing itself as a "social utility." Focus on the latter part while admitting the former, and you, too, can build a successful business.
