Whoa, wait a minute right there sir!

Kent Beck actually works for Facebook.

Martin Fowler is some sort of Principal Engineer or Thought Leader or CTO or Architect or some sort (regardless Services vs Product vs Shipping vs Consultant) for Thoughtworks, an organization that does services and products (check their website :)).

Uncle Bob, on the other hand, is definitely more of a service/consultant person.
