Lafsky has written for publications including
The New York Times, the
New York Post,
Wired, the
New York Observer and
The Christian Science Monitor. She spent a year as a contributor and then associate editor at
The Huffington Post,and was hired as editor of the
Freakonomics blog, which features content by the authors of the internationally best-selling book. Freakonomics.com then became part of
The New York Times Online. In August 2009, following the death of
Ted Kennedy, she wrote a controversial article about the
Chappaquiddick incident, in which she speculated that the victim of that incident,
Mary Jo Kopechne, might have felt that the injustice of Kennedy's not facing jail time was "worth it" because it spurred Kennedy's later social justice work. The comment was attacked by the conservative media.
Rush Limbaugh said on his show that it meant that "liberal young women like to die for the cause of advancing Kennedys' careers." Lafsky responded by criticizing the right wing media for using out-of-context soundbites to stir up controversy. In 2011, she became editor of the
Newsweeks iPad edition. It launched in January 2012 to positive reviews. ==Silicon Valley career==
