Optimism rocks!
Sweden has a pretty damn strong and successful start-up scene, compared to other countries with a similar size (and even compared to some much much bigger countries). One could probably write and read books about the why and how, but it might actually be enough to read this article from Swedish computer magazine Computer Sweden to understand what lays the basis for the rise of Swedish start-ups. Do you feel the optimism and positive attitude? Who wouldn't want to become an entrepreneur or a developer in a country where the overall perception of tech and web start-ups is that enthusiastic?!
