The article only touches briefly on the flaws of brainstorming and group work, but there was a recent article in the New Yorker by Jonah Lehrer that delved deeper into this issue and some of the research behind it. (unfortunately only available to subscribers http://www.newyorker.com/reporting/2012/01/30/120130fa_fact_...) Surprisingly there is decent amount of research indicating that brainstorming is actually less productive than everyone thinks, however the article diverges slightly and explores the history of a few places like Building 20 at MIT where many people from different backgrounds were forced to mix due to the adhoc nature of the offices, etc. Of course I think he referenced another HN favorite, Richard Hamming's classic "You and your research."

It seems that balancing "quiet brilliance" and "keeping your door open" is probably something worth keeping in mind.
