Users of Twitter in Norway

According to Øyvind Solstad at NRK Beta there is somewhere between 20 000 – 40 000 Twitter users in Norway.
The last figure I’ve heard was 6 500, and that was three months ago. Could this be true? If so, and amazing developoment.
Below is the twitter between Solstad at and the journalist Hege Ulstein at Dagsavisen, who wrote an article about Twitter in todays edition, saying Twitter as a place for the elite.
