Predicting the future of learning

I found this interesting tool used by the Elliot Masie group to predict what the most common learning tool in organisations will be in the year 2009. To make things interesting, each mode of learning is given a stock code and can be traded like a proper stock exchange. When you register you 'receive' $5000 to buy stock.

As a 'quick and dirty' overview of the direction people see learning heading, this is quite fun. However, the definitions are too vague for the results to be taken too seriously. For example, I believe that the informal learning afforded by 'Social Networks' within the workplace are the most frequently leveraged tool. But if an organisation sets up an infrastructure that facilitates this informal learning, would that count as E-Learning or Social Networks?

Moreover, notice the wording of the predictor - 'the most common learning tool'. It's true that E-Learning (whatever that is) is on the increase, but how valuable is it really? Why aren't we predicting the 'most valuable learning tool' in the year 2009? Could it have something to do with the fact that Elliot Masie and presumably most of the 'traders' happen to be developers of 'E-Learning'?
