Are there ways social media sites can be designed to be better for the mental health of its users?
I honestly think that the things games do of "You've been online for [insert number] hours; maybe you should take a break" so that users are more self-conscious about the time they spend on social media. I at least think it would work for me, because sometimes, while using social media for a long time, I check the time, realize how much time I've spend on social media, and then I promptly log off.
