Social media broke the internet. Its the ephemerality more than addictiveness. people need to post multiple times a day to stay relevant, or else their content is practically lost. And then they need to resurface their stuff from the past because people just don't see it.
Social media prides on being faster than forums of the past, but we got to wonder whether that's true. a lot of content is recycled in 100 different media, which creates a sense of velocity that is fake. 1000 people scrolling their feeds at 10 posts / hour are not seeing more information than 1000 people browsing 1 forum per day. SM is just fooling them that they get novelty , when they really get slightly colored versions of the same stuff
