He's actually a good astronomer, he just likes to rail against Bad Astronomy. He's especially good at pointing out the scientific mistakes in moves that make you learn more and more about the universe every time you read him.
He's also very excited about science and teaching. Here is his introductory statement on his blog about his mission, as he says, "devoted to airing out myths and misconceptions in astronomy and related topics."
His excitement is infectious as this video shows. As Dale, at The Meming of Life says, "Next time someone starts into the drone about the cold, passionless world of science, show them this:"
It's the infectious passion that comes through and makes you laugh and makes you want to learn more. That's teaching. I got the same vibe from Carl Sagan back in the day. It's a great feeling.
