I started a wiki a long time ago with the ambition to build a repository for Nordic businesses and their use of social media. Now I have finally started to fill it with information and I would be very glad if more people would consider adding links to good cases from corporate use of social media in Sweden, Denmark, Norway, Finland and Iceland. To edit the Social Media Wiki you just sign up for an account at Wikidot.com and then join my wiki with the password “mediaculpa”.
Among the pages that I have started to build, the most extensive list is Swedish businesses on Twitter. It already contains 80 companies (or to be more precise, 80 Twitter accounts, since some companies run multiple accounts).
