Should questions about the user experience of the UX Stack Exchange site itself be on meta or the main site?
Questions about the site itself should be on meta
Questions about user experience are on-topic for UX Stack Exchange
I've come across some questions about the site itself that were asked on the main site: Why are vote buttons on Stack Exchange shown when they can't be used?
And some others that were asked on meta.
Are these types of questions on-topic for both the main site and meta? What is preferred?
