F/M/K: SOCIAL MEDIA APPS

I sincerely hope no one has tackled this topic before. I did a half-hearted search before publishing and didn't see anything. But there are a lot of F/m/k lists.
  1. F@#k: Instagram
    It's so pretty.
  2. Marry: li.st
    We were meant to be together.
  3. Kill: Facebook.
    I don't need to know this much about my former high school classmates and ultra conservative relatives.
