Having followers on Brilliant isn't like any other site. They aren't like Instagram, where the entire point of having followers is to boost your ego and show off how cool you are. They aren't like Friends on Facebook because you probably don't know most of them irl. Followers on Brilliant are like students and those who you follow are like teachers because no matter how smart you are, you don't know everything.
So I had a realization the other day that many people post unique problems that no one has thought of before and those who repost problems which or similar reposts are somewhat looked down upon in a sense for not being original (or at least this is what it seems like). So because the purpose of followers on brilliant is to teach them, I believe that the problem creators should create multiple versions of some problem they post (Not necessarially at the same time) so that people can learn better.
Let's face it, if you do a problem only once, unless it had a very interesting and unique solution, you probably will forget how to do it by the end of the week. This is why text books create so many problems, because repetition helps to ingrain information in the brain.
This is just my opinion, so comment what you think below.
And happy problem solving.
