Three new lines of enquiry that have become of interest as a result of this research and will be suggested. First is the opportunity for better statistical modelling of exploration profiles based on observed Type-Token Ratios and distributions. Techniques from information retrieval might be applicable here. Second is the identification of meta skills for long term learning and whether they should be taught to users. Finally there is the possibility that a technological underclass may develop because of the very long learning times in HCI, and whether it matters.
