I've tried the Google Adwords keyword tool in both Danish and Swedish just to test, but the suggested keywords are not so relevant. Google is not independent in this case, and it seems that they list a lot of the keywords they make money on.
Thanks for that welcome link, too, by the way. It's a good place to get up to date on the structure of WebmasterWorld. However, the links at the bottom are quite outdated - still it's nice to be welcomed. :-)
