For the most part they're just entertaining or whatever can be learned from them needs to be gleaned from watching. A few of the videos in there actually are tutorials. I'm adding to the list all the time so if you like these types of things but don't usually look around for them yourself just check out my list here. Also, if you've seen any particularly fantastic speed-paints, walk through's or tutorials on Youtube for drawing/coloring/illustrating etcetera, comment the link to me! :D
