I agree with the author that nobody cares about whatever content you create, aside from your own marketing value and ability. At the same time, we've created huge industrial systems to harvest your thoughts and reassemble them in return for eyeballs on some site somewhere. Your individual value is nil
Personal authorship and ownership of art and ideas is one of the key concepts that created the modern world. I have no doubt that folks are harvesting this guy's blog, and many more like it.
I don't know where we go from here. Should be an interesting ride!
