I just saw this question. It's tagged with usability and user-interface because it's asking about user interface design (in this case in html but it's pretty platform/language agnostic).
Questions about usability are not strictly about programming and they have their natural home in another StackExchange site: User Experience. Should they be considered off-topic when they're only about design without a specific programming issue (as, for example, stated on this post)?
On the other side we have 790 questions tagged usability (user-interface is too generic to be considered on- or off-topic when used alone).
Are these questions on topic for StackOverflow or - in theory - they should all closed/deleted and/or migrated to UX? What we should do with newer questions? Is usability a red flag for possibly off-topic questions?
