That made me think of being adrift at sea with no drinking water, you’re very likely going to be tempted to drink some of that is available around you, except sea water will dehydrate you even faster. Facebook seems to make lonely people feel lonelier, the sad thing is, if making people feel lonelier makes them use the platform more then there’s an incentive to keep making people feel that way. So even if that’s not Facebook’s intention and the only thing they do is follow metrics then you can picture an evolutionary path that reinforces the same problems Facebook was initially trying to improve.
