What is the points for in this yahoo ask and answer for?

Question

i'm new at this..

Answer 1

You earn 1 penny for every point, at the end of the month, Yahoo sends you a check.  NO, just kidding.  All of this is just for fun.  Many people have lots and lots of points.  After so many points, you advance to the next level.

Answer 2

at the top by your picture you should see your name and under it will be your points, if you click on your # of points then it has all the point values asking is -5 and answering is +2 i think

Answer 3

I don't know. But I do know the more points you have the more options you get.

I also know I'm trying to get to level three...
