The drawings don't have to be original either. A picture with text under it is common and gets spread really easy, or just a photo of Chaim or Rav. Kahane with some text under it also is great for going viral. If you are looking to Nafraudi as the facebook success, these are the kinds of stuff that people share. Not great for educating people, but you can pull 10 in a day easy, and great for getting the word around.
