If you lose contact with someone after deleting Facebook, they were not your friend in the first place. My conclusion after deleting my account four years ago. Getting rid of Facebook was one of the best decisions of my life.
I don't think I agree with that idea. People have different ways of communicating, not to mention I don't think people who do use Facebook as a main communication method should be punished because you think you're above it.
People choosing to use a walled garden are being punished by those who would rather not? You may have that reversed - this isn't about thinking you're "above" a communication method, but it is worth noting that Facebook requires using their specific service while many other methods (phone, email, etc.) can be used from a variety of providers.
So, saying "I only use Facebook to communicate" and expecting others to conform is a bit more naturally presumptuous than choosing to leave Facebook - and it's a fair point that if a relationship can't survive not using a specific proprietary tool, then maybe it wasn't that strong of a relationship.
