NYTimes Op-Ed Editor On Getting Published

http://www.nytimes.com/2013/10/14/opinion/op-ed-and-you.html?_r=0

Basically I think the take away is just keep writing and submitting. There are a few helpful hints.

Rather than just sending it to opinions@nytimes.com, I am always more confortable with submitting to a person.

FYI: Honor Jones edits Private Lives

         Michael Winerip edits Booming

 

If I think of more I'll add them.
