The last Weekend Testers (Australia/New Zealand) was brilliant. Let me urge you to read Marlena Compton's report and the transcript of the session.
This sort of practical implementation of critical theory is long overdue in the testing community, and the WTANZ crew did a great job of using a well-known theoretical tool to analyze and dissect some real problems in some real work.
Compare what WTANZ did with Zeger Van Hese's recent demonstration of deconstruction.
This sort of work, bringing reputable and sophisticated critical theory to bear on actual testing and QA activity, is a field wide open, barely explored, and long overdue.
May we see much more of it soon.
