While I agree because English is my first language and the only one I am fluent in, it must be understood that not all developers speak/write in English. Some really good stuff out there on other sites that cannot be found here because the dev cannot use the forum (English posts only). I agree with the rule by the way, just saying.
I would also add, if getting something for another source in another language, make sure you understand that language enough to know what is going on.
Also agree, plenty of nice kernels on here with lots of helpful devs and users.
