@jtunkelo How about Finland as a Social Media Powerhouse? We've a great history in this field.
Invention of SMS
Invention of IRC
Jaiku and its Social Media discussion tradition
IRC Gallery does have a high market share in Finland (compare with FB)
Mobility and Nokia does now have a Social Media Strategy
Sometu does show that teachers are adapting Social Media
Qaiku needs to be taken International
OVI can be transformed to something big
We've some great ideas about NFC = near field communication with great possibilities in logistics, business management, health care, etc.
Mobile payment is a growth business as well
Social Media can also be used as an Open Innovation Platform (technology enterprises > enterprise 2.0)
Social Media in Community and Municipality Management
Add more items to the list. The Finnish microblogging is a light year ahead of Twitter but it's been a niche because of the active users language barriers.
