Here is a Fun Fact I have not mentioned before, but which shocks most people outside of Norway: Each year, on October 1, the "tax lists" are published. This means that the tax records of the whole country are made official to the press. All the newspapers and the TV channels then make their own pages with interfaces that link to the tax records, so that you can search by name and country and find out their after tax income, how much tax they paid, and their net worth according to bank records. You can go to a page like this one, type in name (in many cases that is enough; if not, you can add the county or the postal code, and voila, you know how much your boss/neighbour/grandpa/best friend made last year. And while the tax authorities only make the lists available to the press for three weeks, the press all make their own copies of the lists so that they are searchable throughout the year.
Yes, it is crazy! While I enjoyed looking up the income of my superiors in my previous job, I can understand why this is seen as a violation of privacy. But it has been like this for several years so I am not sure when or if it will be changed. People even use it to negotiate their salaries: "Well, X makes so much, so I should too!"
Here is an example of a search for "Ole Olsen":
