In college me and a friend of mine went to a comfy restaurant because of their stellar food before he ate he would spend 5-7 minutes taking pictures to post online. This annoyed me endlessly and I didint see the value in behind showing mostly acquaintances (depending on your following) propped up pictures of what you're eating or shots of your face. I saw an article on this exact topic that was outlining the idea that social media (ie twitter,facebook,instagram etc) work subconsciously so that people compare themselves to others the irony however that as with my friend in the restaurant the picture is not faithful as to reality since people ad filters and effects as well as exagorate context to the pictures they take to enhance the perception. The "beneficial" side of social media is dwarfed by everything else. So whats the appeal for you personally?
