Sidenote: Catalonia top level domains (.cat) require the web to be served in Catalonian as well. That's probably why you see the link in the top-right to see it in català (or maybe it's done from a person/group from Catalonia). The TLD has an interesting history: https://en.wikipedia.org/wiki/.cat https://en.wikipedia.org/wiki/.cat Edit: the name of the main contributor is a typical catalonian name, so maybe the requirement is not the main reason for the dual language.
