Some loose remarks:

Interesting to see Ward 'discover' a new wiki variant (listen how often he states that the software he is writing 'wants to be X')

I am not really familiar with it, but I think this could be called 'pragmatic Xanadu' (http://en.wikipedia.org/wiki/Project_Xanadu). It will be interesting of this will be successful, or whether it will eventually run into the deep problems that project Xanadu thought it had to solve to be successful.
