Hi,

This is an interesting paper I've read recently: www.dgp.toronto.edu/papers/m...T2004.pdf

It reinterpretes user interfaces as graphs leading users to their desired information. It's nice model and it opens many new questions like:
- is the path length leading to the information a good measure for judging the 'goodness' of a model (from mathematical point of view and from psychological point of view)
- what should be the exact definition of what they call 'subsumption' in the paper (a constant factor for the paths lenghts?)
