I know exactly what you are talking about. I moved to Berlin from Stockholm. The Nordics is not known for their friendliness, but within the start-up scene or at tech events, networking is not a problem. To be honest, I get the impression that most people are not genuine or confident in their standing within the scene, so lean on those they know, see & be seen, to feel validated. I have yet to attend an event here that has provided much value… but the flyer graphics and promises within the copy are consistently beyond well-done… perhaps that tells us something: appearances are of higher value than true connections and progress in Berlin.
