A long time ago I registered at twitter but never posted any message there. But things are changing and I have started using Twitter, now. You’ll find my Twitter feed at http://twitter.com/mschwarz77en ( http://twitter.com/mschwarz77 is my German one).
Update: Well, I have stopped using twitter any more... sorry for all my followers!
For German readers I have created a German blog at http://michael-schwarz.blogspot.com/ where I’m writing about everything I find interesting.
