How do those apps on facebook predict your best friends?

[misspriss]

How do those app things that you click on predict who your best friends are? like do they look at who comments you the most?

thanks! =)

Facebook is a money making business disguised to look like a "friends network"
You can count on it to sort out your acquaintances into gullibility order.
Nobody "looks" at anything, its all done by computers

They don't know which is your best friend or anything when play game or anything they always say that this person has a higher score but yet they played the game before.

I think they can use your friends when you add a app and you click ALLOW that's how they pick out your friends
