As I’ve observed elsewhere, I think that one of the most significant barriers for newcomers to Tinderbox is that they have used other programs. In my experience it can take a while to see past one’s preconceptions and start using Tinderbox for what it actually offers (which is unique) rather than trying to use it like another program. I found this observation by James Fallows was crucial in my adjustment of my thinking. Tinderbox is best used for associations not hierarchies.
