While Ryan and Gross’s approach appears satisfactory in terms of the specific question regarding how to spread a singular, unalterable, and clearly superior innovation among a hesitant population, it neglects many aspects that become more important for other innovations: How do users implement the innovation into their everyday practices? What symbolic meaning does the innovation have for them? How do they communicate these aspects among each other (and not simply communicate the adoption decision)? When Everett Rogers chose to adopt the Ryan and Gross methodology as a basis for consolidating the various existing streams of diffusion research to a single integrative approach, he initiated a development that led to a long-lasting neglect of these questions and cemented the focus on binary adoption decisions (be it on the level of individual adopters or on the cumulative level of social systems) (Meyer, 2004).
