Oh, wir gebrauchen schon ganz freiwillig die englische Sprache.
[Oh well, we already use the English language completely voluntarily.]
Fact is that German Q&A sites similar to Stack Overflow simply lack the necessary number of users to get your problems solved in a short time. If I want answers, I have to post them here on one of the sites.
If I would post my questions in German, the expected result would be similarly frustrating. I haven't tried.
I've noticed that a number of helpers will silently fix my worst typos (thanks to you) and I can concentrate on the problem to solve.
And all that works without written rules.
