I'm trying to stay away from the social networks, but somehow our local running club decided that Facebook is the best way to communicate with external world.
True, that's one complaint I still hear about quitting is that a lot of events and groups are still managed on Facebook.
I haven't yet deleted facebook, but I only access it from home computer once or twice a week, and as a result I miss some events because my friends keep sending me messages via facebook messanger even though I have post at the top of my page saying I'm not actively use facebook and ask them to use literally any other messaging platforms.
