These two authors continue the discussion on the ideas in their respective books here and here.
I posted the original on this discussion here.
I found it really interesting to read the dialog between these two authors. How the discussion turned. How one asked a question and got it answered.
The next best thing to actually having the two of them together to go back and forth.
Do you think they are as close as Suroweicki states?
What else would you ask them?
