I'm referring to the decades of interactive mind-mapping software (which are both much more feature-full and expressive than Workflowy and have already been marketed as being based on how the mind works--and while mind-mapping is also overhyped it well known and has been studied in education and learning). This comparison gets particularly glaring when you assert that your software is the first ever to do this. I think you're doing Workflowy a tremendous disservice by inviting comparisons with mind-mapping software.
