It's this crazy thing called an "article."

Good, that beats the heck out of a Youtube ELI5 or a slideshow of tweet-sized snippets. A 30-second skim suggests that the writing is of high enough quality to warrant a 10 minute read. Since it is all on one page, I can ctrl-S and read it on the bus. Buses are also good.
