A great article by Timothy Flanders :
“Social media works by giving consolations and then creating attachments to these consolations through “likes,” “retweets,” and “followers.” This may seem unbelievable, but try paying attention to how you feel when you receive these throughout the day. Try putting your phone down for an entire day and see if you feel an urge to pick it up again to check for notifications. Most people feel an urge to pick up their phone and check within seconds of having any free time.”
