Everything i write, post, tweet, blog or blurp is just my personal opinion and is not the opinion or policy of my employer, my cat or my goldfish.
I post in English and German. Will try to mark each post correctly, but errors happen. Sorry for that.
I appologize if I am not following you back. This happens as my stream is already getting more posts than I can read.
