I don't get it. I have extremely intelligent friends who are spending all of their time doing this.
I ignore everything on Facebook and rarely post anything. I read what others write, mostly to keep up with my friends in other places.
Of course, I don't play any kind of games, whether it's on the computer or board games, or cards. I can't sit long enough and also apparently my brain doesn't work in ways that allow me to strategize in games.
