The main problem of this development is the fact that more and more old local people cannot afford the rents anymore and have to move to the suburbs although they have lived in the centre for almost all of their life. A Kiez is changing very quickly: it starts with an abandoned Kiez which everybody avoids - low rents etc. Then creatives come and a scene is developing. Bars/Clubs etc get attracted, more people move there, rents rise, bars/clubs close again -> scene moves somewhere else. Funny is that a lot of my friends who have moved to Berlin complain that their local club/pub has closed (cannot afford rent anymore) but in fact they're responsible for it. Atm Berlin is still an awesome place with a lot of independent spirit but that might dramatically change within the next 10 years.
