I definitely appreciate the raw efficiency of text, and prefer it most of the time. Video has its place too, though. Sometimes it's nice to just relax with something that has moving pictures to hold your attention.
While the Andrewism video doesn't fit into this category, I've been getting more into watching videos for technical topics lately. I was trying to learn about how perceptual image hashing works the other day, and needed to understand the discrete cosine transform. The wikipedia article wasn't going to cut it, but I managed to find this video on JPEG compression (which uses DCT), and it ended up being very helpful.
