Since I did not get a lot of feedback, possibly because wordpress denied to accept the vote, I can now see that continuing the blog in English or German seems to be equally popular or unpopular. I have provided the articles of almost three months almost completely in both languages, but now I intend to concentrate on the English version and provide a German translation for some articles, based on how much time I have and how much necessity I see for this and how many readers the English article gets.
If I do get a lot of votes, I will reconsider this decision.
