As much as it is disappointing, and discriminatory, etc.... StackExchange has a broadly applied Primarily-English slant:
Since this came up on meta, here’s our official policy towards
non-English questions on Stack Overflow, Server Fault, and Super User.
(note that I say “programming” below, but this policy is the same
across all the sites — when reading, you should substitute the actual
topic of the site you use, e.g. “sysadmin topics” for Server Fault,
etc.)
It is not, nor has it ever been, our goal to be the one place in the
world for all programming information in every possible human
language.
Thus:
Direct programmers to native language resources. Users who post non-English
questions should be gently directed to programming forums
in their own language. Community should form around the gravity of
native human languages. (see: Chinatown, Little Italy, etc.) Feel free
to post links to appropriate human language-specific resources.
It is not our goal to teach English. It is our goal to teach programming.
If the post has salvageable English and makes some
modicum of sense, it should be edited and improved just like any other
post. If it does not, it should be closed.
The asker has to put effort into the question. Barging into an obviously
English dominated forum and insisting on posting a question
in another language is no different than the “do my work for me” sort
of programming questions — the worst possible sin on Stack Overflow in
my humble opinion. You want us to give you answers? Then prove that
you’ve put some effort into the question, and you can begin by
politely asking it in the language this community is formed around.
Now, if askers try to use English and put in “sorry, my English isn’t
very good”, that’s fine. Heck, a lot of native English speakers aren’t
very good at it, either! The reason we have collaborative editing is
to learn and improve together. This is totally fine and even
encouraged. (Please do try to make sense, as our users are often
brilliant, but not telepathic as far as I know.)
But the idea that we should be forced to accommodate random human
languages in our community is completely unsustainible. Now if you
want to form an any-human-language-goes community like that, be my
guest. I fully support your effort and we’ll be more than happy to
direct any non-English questions your way.
