Another prob id the way that the developers manipulate the people who use the social media platforms by having them always constantky checking for updates on the site, to check if someone liked a post or shared it, or tagged you...
One of the reason I only use Steemit and Whatsapp to communicate, as well as discord... I use the rest as a way to market ICO's and for nothing else :D
We as people seem to seek approval from everyone else and that is how social media can negatively affect us, because of our desire to be seen as more and we seek the happy emotions that come from people commenting or liking our pics or comments that if we do not get it, we fall into a depressive state which is in turn bad for your mental health...
Nice post :)
