RE: Would it be better to write here in English or in my mother tongue?

At the moment, Quello is more focussed on English questions and answers (from a UI and functionality perspective), however with that said, there is no reason why you can't post in German if you'd prefer. In the future, we'll be looking at how we can cater to different languages more easily, both how you post and find questions on Quello.
