Neither it, nor even Germany/UK/France have a critical mass of tech people or early adopters.
There isn't very strong 'startup culture' anywhere in Europe, unfortnately.
You listed basically all of the notable startups to come out of Europe in one sentence, which is not good.
I've lived all over Europe as well as the US, I'm aware of the differences.
There just isn't a strong cluster of tech-types, nor strong movements of early adopters for most things in Europe.
I will give you Skype though - Skype was a huge hit in Europe in 2004, especially because calling/long-distance rates were so crazy expensive - that's actually a pretty good example of a Euro-based startup hitting the local market well - i.e. 'in their pocket books' where it matters, in a way that kind of transcends national boundaries.
A startup that conquers fast/easy/cheap currency exchange, I think will likely do well in Europe as well.
But it's hard to build early adopters there, unless you hit it right.
