A slight correction to a source

A while back I posted about the poor economic situation in eight states from Oklahoma to West Virginia. It seems the author of the article had to issue a retraction of sorts after various blogs questioned his data. He investigated his sources and now issues two corrections:

* The 8 states are still at the bottom but divide between those 8 states and the ones above them isn't as distinct as his earlier data suggested.
* The comparisons between states and countries cannot be made because the numbers were computed in different ways and the method of aligning the numbers was bogus.
