Credo: Always be asking questions.
Who is Randall Munroe?
http://www.redhat.com/magazine/025nov06/features/xkcd/?sc_cidbcm_edmse=: One of the few interviews Munroe has given as of this date. Linux enthusiast magazine. Fitting place for him to speak.
http://pumix.blogspot.com/2006/10/randall-munroe.html: A small blurb on Munroe and a useful link to his Best Thing project. Also a very good picture of him. Almost quintessentially Munroe.
http://en.wikipedia.org/wiki/Randall_Munroe: An almost completely useless Wikipedia article on him. Links to a few of his other algorythm projects; The Funniest, The Fairest, and The Cutest.
Projects and Contributions?
http://xkcd.com/: Munroe's seminal work. Quite possibly the only webcomic that matters. "When designing an interface, imagine that your program is all that stands between the User and hot, sweaty, tangled-bedsheets-fingertips-digging-into-the-back sex."
http://www.conservegravity.org/: Munroe's important lifelong work for the American Society for the Conservation of Gravity. Truly more relevant than the works of The Gates Foundation, MoveOn.org, and Amnesty International combined.
http://bestthing.info/: Vote early, vote often.
http://blag.xkcd.com/: Randall Munroe's weblog. Definitive proof of the man's intimidating level of intelligence in the entry for December 11th, 2006 "The Map of the Internet."
