In light of this recent question on main (now migrated to meta), here is a question I've been meaning to bring up for a while: should we broaden our scope to allow questions about challenge writing?
I think there's a lot to be said for it. It would probably provide unique content that you can't find anywhere else on the web (but could be relevant to people external to the community, since programming challenges are written in many places), and definitely aligns with the interests and expertise of this community. It could also help improve the quality of our own challenges if we educate each other on how to write better challenges (and thereby complement the sandbox). Also, while we're not a Q&A site I think there's no reason that we shouldn't make use of our Q&A heritage when we can.
Just to clarify, even if we say that we want to allow challenge writing questions in general, that doesn't necessarily imply that the question I linked above is or isn't a good example of that. If we do want to allow challenge writing questions, we should probably define a clearer scope of what sort of questions that would include (only specific questions about specific problems in challenge writing, like other SE sites would accept; only tips-like list question like we have for answering challenges etc.).
There is of course also the possibility to allow them on meta, but meta is about the workings of the community, whereas writing programming challenges is a concept that is completely independent of the community.
One more thing: if we do allow them, I expect them to get something like a challenge-writing tag so that everyone who feels that they dilute the challenge content can easily ignore them, so they can be easily filtered out in searches, as well as specifically searched for.
