Very soon we are going to publish a survey on MDN that we have worked on with our product advisory board members, Microsoft, Google, Samsung and the W3C. To be as inclusive as possible, we localized the survey into 8 languages. General localizers might not be aware of the dominant terms used in the webdev community in those languages, so we need your help to ensure the survey is well understood in all languages.
If you speak Arabic, Brazilian Portuguese, Japanese, Korean, Russian or Spanish, and want to help out, please contact me, so I can share the file with you. The survey is already fully localized into those languages and we are looking for a quality check with an eye on language that is familiar to web developers.
