Just look around in the comments here, you'll find plenty of stereotyping. One thing is important though: Berlin is neither East nor West (never has been after WW2), it's entirely it's own thing culture wise. Your experience in Berlin won't really tell you anything about the rest of Germany.
Why do west germans have a negative opinion of east germans?... I vowed never to return to berlin, hated it, so I'm interested in the reasons.
What does HN think of the scene in germany? I've never heard this.
