My only plaint so far is that Latvia and Lithuania are not included. Estonia is certainly tied in with Finland. But the Baltic countries do have many aspects of recent history in common. Their literature is fascinating. If we can embrace the whole of Scandinavia, disregarding language background (e.g. with Finnish, Lappish and Greenlandic), we could perhaps take on board the other two Baltic countries. If we have visitors from the Baltic states, maybe we could take on board all three.I think that to include Latvia and Lithuania would be stretching the frame of reference a bit too far. Greenlandic literature was discussed because there is a genuine possibility that Greenland might become a sixth Nordic state. As far as I'm aware, there's no such possibility at present for Latvia and Lithuania. Also, as anyone who has visited them knows, those countries (especially Lithuania) are culturally distinct from the Nordic states, and while Estonia can be given guest status here because of its close ties with Finland and Sweden, I don't really see how the other two can fit the frame.
A similar problem occurred in the life of Usenet back in the early 1990s, when the newsgroup soc.culture.baltics was formed as a breakaway from groups like soc.culture.soviet and soc.culture.nordic. I think a separate Baltic literature blog might be a more interesting avenue to explore, and maybe you could think about setting one up, Eric? It would certainly be the first of its kind.
My feeling is that there's a lot of Nordic writing, especially in Finnish and Danish, that isn't familiar to readers from outside the region, and I would rather concentrate on exploring those literary areas, rather than widening the focus outside the Nordic region in the way you suggest.
