What happened to CRC cards?

Back in the early '90s when I got started with OOPs - there were a few object-oriented methodologies (or compilers!). Grady Booch ruled with his classic text on Object-oriented Analysis and Design. There was one approach to object-oriented development that was both pedagogical and developmental (for small projects) - CRC Cards. I recall a CRC tool written in MacApp that layed out the relevant classes and generated the class definition in C++ (or Object Pascal). CRC is not mentioned much anymore - too bad, it was a terrific way to learn about object-oriented thinking and design.
