A Goodreads user asked Josh Sundquist:

How has being a YouTuber influenced your decision to write books? Have your videos changed your content and/or presentation?

Josh Sundquist I've always wanted to write books. I wrote short (terrible) fiction even as a child. But YouTube gave me the platform to get published.

As for the second part of your question, yes. For example, people seem to really like my graph drawings. So that's one reason why WSHOS includes graphs. (Although the origin of the graph is of course pre-YouTube and pre-book; I've always simply interpreted the world mentally through graphs)
