Brotherhood 2.0

i have known John Green through his books for quite some time but had no idea about his or Hank, his brother's activities on YouTube. But then one day, i came across this channel and now I can't stop watching their videos. What have they not covered in those? Starting from their family matters and well through the international ones, the Green brothers communicate with each other via vlogs which have connected millions of internet users in a unique fashion. It's been 10 years now and they have over a thousand videos, and the best part is they don't seem to stop anytime soon. It's all on YouTube and yes, all for free. So, what are you waiting for, nerdfighter or not?
