I just deleted my FB account yesterday. Believe or not, your experience makes me feel OK about it because even with FB, I’ve drifted apart from all but a few close friends. That makes me think it’s the norm and social media doesn’t do nearly as much to keep us connected as it would like us to believe.
Unfriending specific people in a huge cull of otherwise nice and well meaning people you no longer care about but are chained to by inertia is torturous. Much less psychologically burdensome to unfriend everyone by nuking the account and start over with a clean slate somewhere less corporate and shitty.
