The site is BanjoBenClark.com.
No, he doesn’t teach anything about technology or programming or web design. He teaches guitar, banjo, and mandolin.
The site itself is one of the nicest to look at and best organized with respect to menus, that I’ve seen in a long time. Almost every time I look at it, I find something else learn from looking at how it’s organized. I also learn a lot from how he’s leading people to it from his YouTube videos.
