It was a shock when Richard Johnson, the New York Post’s acclaimed “Page Six” columnist of 25 years, left the paper for News Corp.’s The Daily in L.A. in 2010—but now he is returning to New York. He was offered to come back to the Post when The Daily went under last December, but he declined. His new role is still under wraps—he did not respond to an inquiry Wednesday, and the Post did not immediately have a comment. This should be fun.
