how do some people know the answers to every question?

Wikipedia and Google!!!! Copy Copy paste paste!!!! Got it?

no they dont ,if they knew answers to all the Q's they would be doing better things in life rather than answer these Q's many of which are stupid, dumb and senseless. it even surprises me people ask such mundane and senseless Q's.. well as far as the points are considered .. the people who get the most are those with no work other than while away their lives answereing others Q's and trying to garner points , while their own future is a big question marks !!!

Because they troll Yahoo! Answers and only answer the questions that they know the answers to. Plus, people ask really retarded questions that ar easily answered. Like yours!

I think the world is being taken over by super-pseudo smart cyborgs that operate on a diet of Yahoo and crack cocaine

They are probably the best BSers you will ever meet in your life. If they can convince somebody they know the answer, they get the points. Or...they have multiple accounts and they vote for themselves. I thought about that.

It's being well informed about stuffs and know how to play your game well

they don't. they r computer geeks. they know everything about answering questions. they r born that way. u want to become one too? get nerdy.

They probably READ a lot about all different subjects... and have a broad knowlege base.

You know, I was wandering the same thing.

That is just insanity.
