"#Facebook is already an unbearable enough place as of late, at least in my case. Awful national and international news stories continue to appear in my personal feed alongside friends’ amateur political commentary and personal quibbles, and that mix makes the occasional ray of satirical, hilarious sunshine from off-kilter sites like #The_Onion welcome. Sadly, Facebook has begun trying to ruin even these fun articles by appending their titles with a “#satire” tag."
