Interesting article but I fundamentally disagree with the notion that the excellent school system is the cause of the good English skills of the Dutch (which undoubtedly exist). It's far more likely that the major reason is the non-subbed TV/movies imo (well a combination of both)

I've always associated the Netherlands with being a tech saavy nation. They always had a vivid hacking scene for example. Additionally the Dutch tend to be citizens of the world and pretty open minded which is a good mix. I completely agree with the assessment of Amsterdam. Nice city, not overly expensive, pretty great for youngish people -> good competitive edge (Berlin is similar but Amsterdam has more of a startupy general vibe imo).
