Last year, the pseudonymous writer behind the SlateStarCodex blog abruptly shut it down, claiming a forthcoming story from The New York Times was going to reveal his real name and potentially put him in danger. Reporter Cade Metz says he was able to easily find the blogger’s real name —Scott Siskind— online. After a farewell post on the blog, Metz says he and his editor were harassed online by its angry fans. Now, Metz’s reporting on SlateStarCodex and the philosophical views that made it so popular is finally here. It’s a compelling look at the mindset among many in Silicon Valley’s tech industry.
