L/F Ratio
Your L/F Ratio is the percentage of your Facebook friends who are too lazy to even look at your profile picture. It’s just likes divided by friends times 100. You’re probably not popular.
20 likes, 200 friends = 10%, you’re barely worth the effort.
10 likes, 100 friends = 10%, you’re a ghost.
5 likes, 50 friends = 10%, you’re the worst.
