If people stop using Facebook, is anyone around to like its posts? I stopped using Facebook (though still use Instagram and Whatsapp) and my life is much the same as it was before. And here's the secret - I'm not even loyal to Instagram or Whatsapp, more to the network. If friends fall off Facebook, then there's even less reason to go. In fact, Instagram has entirely replaced it for me. And if Photos on iOS had a public sharing feature, I'd probably just use that, and then fall off Instagram too.
