one of the main problems is that a big part of the crowd is not open-minded. an example:

bitstream played here last june. berghain is a techno club and there is always played 4/4 stuff. so i quite wondered they had invited bitstream. the dj who played the warm up (i really admire him cause he always plays fantastic stuff) made a really big mistake. he played 4/4 stuff all the way although he should have known that bitstream were an electro/idm act. so when they began their set after 5 minutes almost the whole floor was empty. only cause the played (really brilliant) electro. i mean it is ****in electro. its not so far away from techno like breakcore for example. how stupid can people be?!

lots of the (local) djs dont have the nuts to play some different stuff. one of the reasons is the little story i mentioned above.
