To (mis) quote TheMinimalists [1] they frequently mention that most relationships are born out of proximity and/or convenience. Facebook, with (many times) meaningless word exchange (I can't call these discussions) trick us into thinking them as friendships. This is the convenience part, combined with Facebook nomenclature ("Friends") also helps to that direction. I quit FB approx 2 years ago and Instagram 1 year ago. I don't miss any of the 250 'friends'.
For the 5 people I care to keep in touch frequently, I have installed Signal on my smartphone and my PC and we chat very frequently (when we don't meet)
