I can't imagine living without my art, for Youtube to be this all-encompassing entity it seems to strive to become, such "basic' features as visual arts should of course be included. Where would we all be without art?
Filing us away under "how to and style" is too easy. I've made about 50 drawing videos, NONE of them being a "how to draw" video. I don't see them filing away all the video clips of famous singers in the "how to" section.
