I used to post here at least one question a week. Within the last few years, it has felt like the community has changed and the moderating has changed. I stopped being as active and watched questions to better understand what was being encouraged. I believe very strongly that each community member needs to support the policies or leave.
I stopped posting questions here and took my questions elsewhere. Recently, a thought occurred to me on approaching the collatz conjecture as a combinatorics problem. This is probably an obvious point but it was not obvious to me and I thought that either I would learn that this does not work or works well and has already been well explored.
I did not see this covered in wikipedia or in other sources.
I raised the question here.
Today, that question was closed as not relating to mathematics.
If this is the appropriate response, if someone could explain to me how this question is not about mathematics, I would greatly appreciate it.
If this is a web site solely for standard homework problems, problems about understanding published math papers, or problems about standard mathematical concepts, just let me know and I will restrict my future questions to these 3 areas.
