Something (weird) that I noticed in many Scandinavian websites is their short domain names. I don't know the reason, but I like the fact that you can type 5 letters and access the service that you want.
Nothing gets Norwegians arguing more than wolf politics.
Small nitpick, but you need to be a Norwegian resident with an ID number (fødselsnummer) and a postal address in Norway, not necessarily a citizen.
I could imagine acronyms just make more sense if long words like that are common in the country.
"Lokomotivmannsforbund" = "train engineers union" :)
We also commonly make up compound words on the fly making it very hard to use things like swiftkey without typing the two words and then removing the space as they are in no word list.
