BDD is "customer facing". It's _supposed_ to be about writing the tests in terms 
a civilian client could understand and agree on.

And it's about keeping the entire program out of your mind all at once. It's 
about making changes while looking at a huge application like a map thru a soda 
straw. I want to make one little change, in one corner, without worrying that I 
will derail some other far-flung part of the app. Its tests will defend it.

Good stuff snipped!
