This is not a get rich quick method of making money- very few of them are and most of those are not legal! But if you have special knowledge to share with a niche crowd you can build a very loyal audience over time that will come to hang on your every word and more importantly buy your products and services once you start charging for them. This is what Strength Running was built on- it started as a blog about overcoming running injuries and grew into a 200K+ audience of loyal readers who now buy coaching products and personal coaching services allowing the owner to make a full time living from what started as just a passionate side project. And the cost to build this audience was only time- virtually all of the traffic came just from producing top quality original content- a system anyone can follow!
