Cara talks nerdy with master of teh interwebs Hank Green (SciShow, CrashCourse, vlogbrothers, etc, etc, etc). He describes his love affair with science, how crowd funding is changing the way we create really good content, why people can be so awful on the internet, and all the hard work YouTubers put into their craft. Also he is very funny. Follow Hank: @HankGreen.
