I agree with the broad strokes of your comment, but I have some nitpicks. I think it's culture that's holding the European tech sector back. Investors in Europe are generally very risk-averse and anything that's less than 100 years old isn't really taken seriously. It's fascinating to see how the more neophile countries pull ahead of the rest; how much financial conservatism holds the economy back. When Germans invest, they think mostly of dividends, not growth. And Germany is reasonably sane. Many countries (Italy, Spain) don't have functioning stock markets at all.

I so agree. This is a VC blowing its own horn and disguising it as information. Painful.
>the craziness of the continent
Britain isn't especially rich by European standards (poorer than Germany). London is a deviation. People are flocking to London, not away from the continent. Britain is pretty average in the European silliness contest. We're talking about a country that doesn't have a written constitution or equivalent thereof.
