Tim Urban writes at the awesome site, Wait But Why. He's written some of my favorite pieces, including: The Fermi Paradox, Artificial Intelligence (Part 1 and Part 2), and the 10 Types of Odd Friendships You're Probably Part Of. He was interviewed at Fast Company and talks about the Buzzed-ification of the Internet and what it takes to obtain and retain loyal readers.
If you can blow someone's mind—really, genuinely blow it, again, in a really well-written way—then that's something they want to share.
I discovered Wait But Why by stumbling upon their series of visiting random places. I found the articles super interesting and signed up for their newsletter. Every article they post is a must read. Since adding this to my RSS feed, I've read a lot of their articles. I could seriously spend a whole afternoon reading, and rereading, their posts. If you're in any way fascinated by North Korea, if we are alone in the universe, or the future of the human race, look no further.
