A few posts prior to this, _BOB has asked that links to original articles be included. This one is lacking any identifying information at all, and is therefore subject to deletion, which would be a shame, because it's a good article. Please include the original URL somewhere in the message (either as a link or explicitly stated) so that those of us who like to follow up on things may do so, and also so that the article's author and/or web site and/or employer gets a nod for hosting the original story.
