If the goal is to get more people coding, the biggest problem that I see few people (besides Hartl) solving are getting people from absolute zero to a deployed project. For web dev it means starting at a computer with just a web browser and showing them how to get a functioning site running which you can send a web address to outsiders, even a very, very minimal one. The definition changes with robotics, or other coding disciplines, but the absolute key is developing tutorials and tools which help people go from zero to minimal app deployment. Once you get someone there, they can build on it using tutorials.
