Found two of the topics here very valuable:
Chan Zuckerberg initiative: incredible but like you said, someone will find a way to be skeptical about it.
The Economist profile about the big companies — good coverage and provides some very good insights and information. The comparison of “new” economy with “old” made me read it twice to make sure I was not misreading it. That shifting weight chart is stunning, took me a while to figure it out though :)
