Norway is great for data privacy, however as you say, there isn't a Silicon Valley or anything similar, even in Oslo. There are some good tech groups, and some good university groups spread around, a good amount of design and media organizations, and a much larger percentage of the population know what Twitter and Facebook are and use smartphones, and youth are basically acquainted with most 4chan memes. The biggest and most notorious tech group really is Opera, which also accounts for a significant chunk of the country's data traffic (Opera also operates a very huge proxy service for mobile devices).
Despite what I'd consider to be a fairly (in U.S. terms) progressive government organization that is pro-privacy, Norway has recently enacted its own local version of the E.U. Data Retention Directive.
It could be that this is just a separate world though. In my world, I wish to opt in and choose what I share. Perhaps in someone else's world, they wouldn't even consider not sharing something. Following what my family on Facebook do certainly convinces me that at least some people think that way.
For me, on the other hand, Facebook has put a ton of friction into sharing. Although I am a normally candid person, I find myself overconsidering whether or not I really, really should post what I'm about to. In the end, I go with self-censorship.
