I've got a wide variety of social media usage among my friends and family, so I don't read much into it, but I derive endless enjoyment from:
- people going on social media to announce to everyone they know that they don't care what anyone thinks of them
- people going on social media to announce to everyone they know that they've been outsmarted by a math problem designed for an 8 year old (this one's died down a bit)
- my wife's cousin who, thanks to those fake Learning Channel "documentaries", now gets into long, stubborn Facebook arguments about her deeply held belief that mermaids are real.
Those plus my friends who post weird art and design stuff I'd never see otherwise are well worth the time investment for me.
