There was that Danish school friends site that shut down. Now I'm unsure of anything Scandinavian, other than blogg.se and blogg.no. But with the emergence of a triumphant Facebook, the one good thing is that the girls up there recently discovered Instagram. In the past month or so, I've started to notice more and more Scandinavian girls posting Instagram photos.
The usual Scandinavian search terms, including ones such as tisser and tisspaus, are becoming viable at followgram.me and statigr.am. See this, for example:
