I agree that in many cases it shouldn't be a problem. But if everyone has one or two real friends who might be disappointed, that's enough to destroy the idea.
But it probably depends on whether people use social networks for managing a broad range of contacts or to keep in touch with close friends and family.
The general problem is that some things can change dramatically as soon as they become explicit, even when nothing of substance has changed.
