Randall Munroe — American Cartoonist born on October 17, 1984,

Randall Patrick Munroe is an American cartoonist, author, and the creator of the webcomic xkcd. He and the webcomic have developed a cult following, and after leaving NASA, he became a professional webcomic artist... (wikipedia)

It's tempting to just write a comic called 'Everyone Mail Randall Munroe Twenty Bucks' - maybe it would work, and I could just close down the 'xkcd' store and sit on a beach and draw pictures and make snarky Reddit posts for the rest of my life.
I used to work at NASA in Virginia. It was nothing glamorous; I was just tasked with making code compile for obscure projects, and I wasn't very good at it. Now I spend most of my time drawing pictures and looking at funny things on the Internet, which in retrospect is largely what I did at my old job, too.
Google owns YouTube, and recently, I drew a comic about an idea for a YouTube feature - which they actually took seriously and implemented. So I'm thinking that maybe we'll have a future where Google is 'xkcd.'
I don't have hard numbers about this, but the impression I get is that the amount of eyeballs you get from being on the humor shelf at Barnes & Noble - it is almost insignificant.
I learned very early on in life that not everyone wants to hear every fact in the world, even if you want to tell them everything you've ever read.
