Now, you really have to put my directory listing example in context. 
This isn't about perfect data (such doesn't exist) it is all about the 
ability to create and share data. FWIW -- of all the files to pick, you 
picked the one created by my 12 year old son :-)

Yes, he is a Pats fan, so I used that to pique his interest en route to 
teaching him Turtle.

As I said, you somehow you stumbled across the Turtle doc produced by a 
12 year old. That file was all about getting him going and then showing 
him the implications of his mistakes etc..

My other Turtle tutorials include sample links to profiles documents, 
stuff I like etc.
