So I'm one of those "websites coming out of nowhere" that teaches people to code web projects in Rails (baserails.com). I chose to use a video screencast format because it's the easiest way for people to watch what you're physically doing on the computer screen and then follow along, something that's difficult to convey with just written text and images.<p>Are you looking for more in-depth content on syntax/framework/theory? Or just more curated written tutorials that's mobile friendly?
