What about people who don't speak English?
I met SuperBetter a few days ago and I think it's awesome! Since English is only my second language I immediately thought about people who don't speak English but would appreciate the help SuperBetter can give.
For a start, I would be more than happy to translate the site into my mother language, Hungarian, absolutely free of course. (I've been studying translation at university for a year now, so I have some experience as well.)
I'm sure people with other mother languages would gladly do the same, and adding some more languages to SuperBetter would not only be beneficial to the site, but there would be a whole new range of people who could get that kind of valuable help that they can't get from somewhere else.
Also, according to Nelson Mandela: "If you talk to a man in a language he understands, that goes to his head. If you talk to him in his language, that goes to his heart." Let SuperBetter go to the hearts of people! :)
