Yes, for an organization with the breadth of focus as the Post, having a single person make themselves into an expert creates both an asset and momentum. Happens all the time in journalism. Heck, that's how they were so influential with the Nixon criminal activity known as "Watergate."
Yep. Journalism/news media were deserving of consideration as "the fourth estate" when investigative journalism and truth were considered pillars of their being, now they are entertainment entities. I'm truly grateful Sally Jenkins are still working to keep those ideals alive.
