Query: Uneven approach

As a knowledgeable architect wanting SME, this did not provide much help for me. Plus: OK treatment of BPEL and reasonable examples of code. Con: Riddled with ridiculous and poor cartoon illustrations. Too many descriptions of services as probable recapitulations of author's projects. Flow diagrams disorganized. Instead of teaching a subject area, this is a 1st person memoir of uninteresting, unchallenging projects.
