Well if an area is totally unihhabited is it REALLY necessary to have broadband there? Kentucky is very rual outside the "big" cities. In areas where there aren't any people I don't think ISPs should have to put in broadband to make a map look fuller.
Any broadband mapping would have to include a reasonable definition of minimum population density such as XX/square mile.
According to their metadata, that's just 2000 census info. Very out of date. Here's something interesting though... This is from their map server. Looks like ConnectTn is a lot more than ConnectTn.
