Each YouTube channel is introduced with a short description and screenshots. There is also a link to the YouTube channel, so you can quickly go to YouTube and check out these videos for yourself. Their list currently has fifty channels, but they are planning to update their list periodically. It's definitely worth bookmarking so you can keep checking them out for new YouTube resources.
