When Ezra Klein joined together with Matthew Yglesias and a handful of similarly hard-working, earnest young journalists to found Vox, they pitched it as an antidote to ideologically slanted news. Vox would differ from the online competition in offering empirically based "explanation and analysis," which Klein, with characteristic modesty and self-deprecation, described as adding "a drizzle of olive oil and a hint of sea salt" to the "spinach" of straight-up news. Nearly fourteen months after its launch, Vox's plan of serving up lightly seasoned, vitamin-rich leafy veggies appears to be working out, with traffic running far ahead of Nate Silver's FiveThirtyEight, a similarly data-heavy site launched around the same time.
