It's not every question (some are just plain bad questions), but I believe that most questions tagged development-process and a good number tagged methodology should be moved to Programmers. I could vote them all off-topic or flag all of them that I feel should be moved, but that seems like a headache. Votes might not get enough to move, and flags would just bombard the mods of SO. What is that the appropriate thing to do?
What is meta?
- Any Stack Exchange user can ask a question
- The community provides support, votes on ideas, and reports bugs
- Your voice helps shape the way Stack Exchange operates
There is no way to do a mass move. If there were, I wouldn't recommend using it.
For one, we don't want to spam Programmers with 2-year-old answered questions that would push new questions off the front page. There's very little to be gained by that. We prefer to let the sleeping dogs lie and migrate things in on a case-by-case basis whenever the need arises (i.e. someone posts a question to Programmers that was answered well on SO -- we then ask SO mods to migrate it over).
For another, we have to be careful with quickly migrating old questions: because they might be off-topic on Stack Overflow doesn't mean they will be on topic or constructive for Programmers. Judging each question would be a pretty major undertaking, which is why it's generally not done.
If you come across questions that you feel absolutely must be on Programmers, flagging for a moderator to move them is likely your best bet.
