For me, it's because when I am bored or feel bad instead of opening a tab and watch P I open this site and just read some stuff and respond to people. And for people who are socially isolated it may be a cool way to get back in touch with people and wake up their rusty skills!
For me its more like i no i pmod but its not the end of the world i got you guys to make me feel better and to reasure me that the grass is greener on the other side! Stay strong!
