Berlin has a problem that everyone will feel it after a while living there: Its scene roots are still very anti capitalistic. This still influences the culture there, even CCC and other "digital culture groups". Still many people don't want to earn big money because they don't want to lose there scene credit. It's creepy, but still many of my Berlin colleagues think that way, especially in the CCC and pirate party orgs.

Hamburg and Munich are much more focussed on deliverying value, real products, make money. They aren't cool, they're expensive and tight. You have to deliver there or you will run out of money very soon (pressure => focus).

Imho Berlin needs to evolve without becoming the next Munich or Hamburg: Leave enough room to have a decent living/start up, to do experiments without having to burn millions for nothing (fancy rooms) — but also be able to rise money and go big, if there opportunities are there.
