I use Facebook to keep in touch with old friends and sometimes people organize events and they invite me on Facebook and it works and makes my life a tiny bit better.
I usually go to the chat directly. Having missed several event invitations in the past two months, I now try to check the notifications every couple of days.
Infinite scroll perhaps twice a month and ruthlessly block whatever I don't enjoy.
Then you submit a post on FB that none of these old friends or acquaintances like or comment on and wonder why you suddenly feel like a leper afterward.
