Lots of people I know spurn Facebook but use Instagram. Nearly everybody I meet on Fortnite communicates off-game via Snapchat. I personally get my internet dopamine fix through Reddit and Hacker News, and if I want to stay in touch with friends, I call/text/email, like the good old days of like 10 years ago.
I don’t see a general global social network around the corner gearing up to dethrone Facebook, but at the same time I am noticing social media usage splintering across a myriad of sites and apps, instead of being dominated by one giant social network.
