I ask moderators to be very careful when migrating questions to Stack Exchange websites. When in doubt, please close questions as off topic, possibly with a comment suggesting one or a few candidates of websites, and let the asker decide where to ask.
Note that we have been frustrated by the fact that some questions are migrated to cstheory when they should not be. We should not do the same thing to other websites.
Here is a recent example: Is there a program / app / algorithm that can sort items using manual choices and deductive logic?
This question was recently migrated to Stack Overflow, but I cannot see any programming aspect in the question, and I think that it was wrong to migrate it to Stack Overflow.
In fact, this is a question on query complexity. Since it is too basic (the Ω(n log n) lower bound is well-known and sometimes even covered in undergraduate courses) and the asker had posted the same question on math (thanks to Yuval Filmus for the link), I think that it should have been closed as off topic.
