For instance, one issue that tends to fascinate is why silicon valley is so far ahead of everyone else. I read an article (in BusinessWeek, I think) about tech centers in Europe -Barcelona and Copenhagen were listed.
I don't feel any particular need to escape San Francisco, which I absolutely love. But I've heard Copenhagen and Barcelona are extremely cool cities, and I'd dig checking them out.
Problem is, many of the elements of the Danes's happiness might night work well with startup culture. There's a powerful welfare state, and a high degree of homogeneity in the populace. Silicon Valley thrives on risk, failure, and diversity.
Who knows, maybe the Danes are too happy to be a great startup center. Maybe startups are a great way to build wealth, but not happiness, and in the end, they end up hurting a region. Or maybe that's all crap, and the happiness of Denmark will cause just the right people to move and/or stay there, and build an incredible tech community...
Either way, it seems like a good topic for conversation on hacker news.
