Dear Susan Cain,
Your article, The Rise of the New Groupthink was interesting to read. I believe many of the issues you mentioned did not acknowledge the other side. You mention the issue of workers not having private spaces. I believe that workers may enjoy community places to do work, like a conference room, but also value having their own space. I believe this is why many workers complain about the open-plan office, not the fact that they must collaborate with other works. Also when people do have work they need to complete individually, it can be distracting to see and hear all the rest of the company at work.
However Andrew Keens chapter The Great Seduction in his book The Cult of the Armature has a different point of view on the impact of Wikipedia and the Internet in general. His example of the cause of death of Ken Lay makes you think about the content that is on the site. If there are some people dedicated to publishing a particular fact or lie, could the truth be lost on this site that so many people use for information?
