"“In the early days, I bought into the idea that the Internet would lead to a better world, that the truth was out there and that we didn’t need gatekeepers,” he said. The idea that he and many others embraced was that an unfiltered Internet would create a democratic information utopia. “Now,” he continued, “I think it’s more complicated than that.”
Medium is Mr. Williams’s version of a gatekeeper, albeit one that relies heavily on technology rather than human expertise or taste. While it has some editors soliciting and promoting some content, the bigger idea is to use algorithms to help identify blog posts that readers consider valuable and to bubble them to the surface."
