Good question. So far, I don't. When I go live and get some success, then I'll handle other languages. Actually, the user interface (UI) is so simple to use that people who don't know English should be able to use the common 'interface experimentation' (that I don't like and that I hope my English language users won't have to use) to see how to use the site. But having versions of the site for languages other than English should not be too difficult. I'm writing nice code, but it's not the most general thing since Einstein's theory of general relativity, and with enough changes for languages, small screens, etc. might need some 'refactoring'. So be it.
