this question has a suggestion to migrate to ux.stackexchange. This seems quite reasonable, and ideed its not uncommon to se UX questions here.
Given that programmers and UX are full sites would it make sense to have ux.stackexchange as a migration target?
there is also a ux tag with only 9 questions and a search for ux shows another couple of hundred questions (one of which is already migrated to ux)
