Deborah Hartmann is using Ron Jeffries' quote at the foot of her e-mail.
"My advice is to do it by the book,
get good at the practices,
then do as you will.
Many people want to skip to step three.
How do they know? " -- Ron Jeffries
I like it.
I don't like people who make a judgment of something they never practiced only by reading about it or even just by hearing about it. For example, I don't like people who criticize Agile software development practices simply because those practices sound unfamiliar to them.
