it's missing a blob of elfdalian at the northwestern end of the dalecarlian blob. crazy dialect.

also most of the blobs of "swedish" in the north of the country would not have been recognisable as swedish from people further south. pitmål and kalixmål are basically unintelligible.

overall the original thread seems to have way too many people finding fault with the image for it to be in any way authoritative. at least the creator is willing to do more revisions.
