Over the past several months, we have received an impressive number of challenging, clever, and fun problems from all of you. Writing good problems is hard, and we have been inspired by the number of you who are willing and able to produce great ones.
The problems you all have submitted have taught us that only a small portion of problems that people write, are problems that fit our very strict criteria to be featured in our problem sets. What they have also taught us, is that our strict criteria excludes tons of interesting problems that all of you would find fun to solve. Further more, if a math problem is unclear, or needs work; it would be much better to have the community provide detailed constructive feedback on the problem, rather than be dismissed by us.
Over the next several months we will be working to reinvent the way problems and discussions are published and disseminated on Brilliant. We would like our members to have the ability to publish problems, hosted in our interface, and disseminate them to the people they like solving problems with on Brilliant. Unfortunately, this will take awhile to build.
We have taken down the problem submitting button, to divert our efforts toward enabling problem publishing for everyone. The time saved by not having to maintain the currently inefficient process of problem submission, will be better applied toward making the site experience better for everyone.
In the mean time... if you have a good problem that you think others here would enjoy, post it to discussions. If they are disciplined, your audience can avoid looking at people's answers until they have tried to solve it. While not the same, it somewhat approximates the experience of our weekly problems.
