premise: David Plotz (born January 31, 1970) is an American journalist and is currently the CEO of "Atlas Obscura", an online magazine devoted to discovery and exploration. A writer with "Slate" since its inception in 1996, Plotz was the online magazine's editor from June 2008 until July 2014, succeeding Jacob Weisberg.
hypothesis: Jacob Weisberg was an editor from June 2008 until July 2014.
reason: I think it was difficult for the system because of me excluding the fact that Jacob Weisberg was the editor before David Plotz who actually served before June 2008.
