Tim Urban’s blog, ‘Wait But Why,’ looks different than most sites you might visit nowadays. While most publications are trying to keep their articles short and sweet, Tim regularly dives deep on his topics, writing thousands of words on a given subject. Plus, he illustrates every post -- not with modern, sleek graphics, but with hand-drawn stick figures.   In this episode, he explains just how he racks up a million pageviews regularly, how he builds and maintains his audience, and why not being an expert on something might make you better at teaching other people about it. Plus, he tells us about the prehistoric musical he was working on before starting ‘Wait But Why.’
