I came to the conclusion that I should leave Facebook quite a while ago now. However, almost all of my friends have and constantly use Facebook, and it remains almost their sole method of contacting me. My friend group and I are all around 16, so that likely explains things.

I'm not sure. Aren't teenagers supposed to be the demographic most likely to change networks?

There is an element of inertia and of being held hostage though. Why go through the hassle of everyone changing networks of Facebook still works? And no-one can leave on their own...
