For those of you who want to run a 15k/month one person business, the most interesting excerpt from this article:<p>> Since I had been publishing content to GoRails for a year before I launched the paid courses, I had the advantage of all the SEO and visitors I had built that year. During that time, I was collecting email addresses of people interested in learning more about Rails. This gave me an audience I could launch to from day one, which was incredibly important to give me some confidence as I launched.<p>> After getting some initial traction, I had to come up with a way of marketing my screencasts. The way I solved this was by pivoting to weekly screencasts and releasing a free one every other week. This let me share quite a lot of content on places like Reddit, Rubyflow, and to my email list. I knew those users would check out the other episodes I offered and hopefully subscribe to the paid content eventually.<p>> I would say the majority of growth of GoRails has just been from this free content. If I cover a popular topic, it often gets shared, and if I cover a library, the authors love to share the videos as well to get more usage of their own work. I'm uploading the free content to YouTube which not only gets me an audience there but also saves me from some very high video hosting costs that I would incur if all the free content was hosted on Wistia. It makes for a nice way of building the community and the customer base at the same time.
