I was a big user of tiddly wiki back in the day and a fan of the work. One point of distinction for Dendron - we are hierarchy oriented but support other means of organization (tags, backlinks, graphs, etc). If you're trying to create a model of the real world, you probably want to use a graph primitive to capture the nuances. But that flexibility is what makes things hard for humans - since a note can exist in N places, how do you find it? How do you even know you've tagged/linked it correctly? Dendron's constraint of hierarchy is one of those "its not a bug but a feature" things - the constraint of hierarchy makes it easy for humans to reason about. What we add on top of that is the ability to refactor that hierarchy when necessary
