Here is why the point system should come back.
Brilliant.org, in the past, would reward you prizes after scoring enough points.
I think that the rewards should come back because they provide an incentive to solve math problems on this website everyday. Sure, most people come here to learn, study, or practice math, but their overall objective is the same as many others who are good at math: It is to work for that 25,000 points and receive a prize. It provides that extra push to come here and solve the hardest possible problems.
Newcomers may ask themselves: Why do I need to solve problems here if I can just as easily sign up on a different website that provides the same needs?
My answer to this early on, was mainly the prizes and then the interesting problems.
Now, I ask this question to myself now: Why would I need to solve problems here every week if I know most of the material and is already in the higher levels?
Ok, I'm done. Sorry for the overall negative (and biased) point of view and thanks for taking the time to read my post.
