I have always been interested in particle physics, though I have no formal training in it, and this cartoon is a bit of an inspiration that some science training doesn't go amiss when communicating with the public - he seems to have a firm grasp of the science while also creating an informative (and fun) video.
I hope Jorge is making some money with his various endevours; when I saw him speak at Princeton some years ago he definitely had a job other than professional cartoonist. I know his books draw a profit, but really, when your primary audience is grad students and all the content is available online, you can't expect too many sales. His Wikipedia page makes no mention of his "day job", however.
Informing people about science seems to be a new direction for him ... perhaps as his audience moves out of grad school and into the world he'll find an increasing market for scientists wanting to find new ways to communicate with the public.
