A quick link and intro to the Vlog Brothers, John and Hank Green. John Green is the remarkably talented writer behind The Fault in Our Stars and Hank is his brother, who is a musician who also works for EcoGeek. Together they create regular videos for YouTube about everything from “How to Become an Adult” to “The 5 Worst Typos in History.” If you are between the ages of 10 and 16 then you already know about the Vlog Brothers. I thought maybe the rest of you should learn about them too. They have over 1 million subscribers and their enthusiasm and dedication to their audience show no signs of waning.
