I believe at least in all of Eastern Europe (including those guys who call themselves Central :wink:) US English dominates in pop culture, and business. I also used to work with a few Italians, and Portuguese and they all wrote US En too, so I suspect it's the same for them too.

Those who call themselves Central Europe are a part of the European Union, and so lean towards the UK English since school education and relevant English certifications are geared towards it. Perhaps those who would like to ignore the fact that Central Europe is a region distinct geographically and culturally from the Eastern Europe, nowadays more than ever, should not project their views unto others and speak for them?

"Here" is Poland, but in my trips to other places in Europe (and around the world), I never saw anything that would suggest this is an unique experience. On the contrary, it's pretty much self-evident, and having it be otherwise would require the last 200 years of world history to be dramatically different from what they were.
