This helps us to the full use of the world wide web and is also easier to find us in all international social networks.
Our declared goal is that many more people from all over the world can understand our content.
It just makes sense to use the most important language in the world. Many vocabulary are already familiar and we come across the language regularly in everyday life - so no worries ;-)
BUT of course we love and cultivate our mother tongue, by the way, we have a few of them with our team from 6 different nations.
