See, and that's what I've wondered about as well: missed opportunities. Thankfully I have lines of communication to everyone I actually want to talk to outside of Facebook, so I really haven't lost a beat.
I was addicted to it the same way most people are. Scrolling aimlessly, getting into pointless arguments, etc. etc. Even the memes weren't worth it. lol
Heh - most of those memes aren't worth the screen-space they're printed on!
