There were many excellent articles published during the course of 2010. It is hard to choose the best, but here are my top 10 (in alphabetical order by the author's last name). I'm not saying I agree with everything in these articles, but they were definitely thought-provoking and addressed important issues of our time.
"What good is Wall Street?" The New Yorker, by John Cassidy
"Oh, the humanities! What the liberal arts are good for," The New Republic, by Rochelle Gurstein
"Urban legends: why suburbs, not cities, are the answer," Foreign Policy, by Joel Kotkin
"Beware of Greeks bearing bonds," Vanity Fair, by Michael Lewis
"The crisis of middle-class America," Financial Times, by Edward Luce
"The myth of charter schools," The New York Review of Books, by Diane Ravitch [review of the film Waiting for "Superman"]
"The end of men," The Atlantic, by Hanna Rosin
"The thrill of science, tamed by agendas," The New York Times, by Edward Rothstein
"Progressives against progress," City Journal, by Fred Siegel
I consciously did not include any articles from spiked, nor articles by spiked contributors in other publications. 2010 saw many, many great pieces in spiked, but a highlight for me was the "Question Everything" series of essays. You will find the first one, by Frank Furedi on education, here. At the bottom of his essay you'll find a list of the eight others.
