Taking on the System: Rules for Radical Change in a Digital Era, by Markos Moulitsas Zuniga (2008, Celebra), purposefully and transparently is a 21st century update of Alinsky’s Rules for Radicals: A Pragmatic Primer for Realistic Radicals (1971, Random House). Where Alinsky summarized community organizing techniques in phrases quick enough to fit on a bumper sticker (“Make the enemy live up to its own book of rules,” and, “Ridicule is man’s most potent weapon”), so does Moulitsas (“Bypass the gatekeepers,” “Raise an army,” “Target your villain,” “Craft your hero,” et cetera).
