He does how-to videos too which I'm personally less interested in but sometimes there is a subject I want to know more about. He also has a podcast.
Speaking of podcasts, Margaret Roach has a nice one for driving to work or walking the dog called A Way to Garden. It is actually a radio show on one of the NPR stations - Robinhood Radio. Ken Druse had a similar one but he stopped making new ones and pops onto Margaret Roach's podcast for Q&A's.
