I regularly travel to different countries and language regions and often need to access information online. Although I understand parts of some other languages, I prefer to use English because I operate fastest in English. I have my browser set to English and this delivers my preferred language to the websites I visit. But they don’t all respect that.
I am amazed at the number of international websites that use my location information and then assume I want to use the major language associated with that location. I don’t! I want to use my preferred language.
If you have a multi-lingual website, please make it user-friendly (or ask your web developer to help).
