I understand that for the author of the article the goal is to make a product that people use and that entails a financial return. I just want to say that building a software from scratch, even if doesn't end up used by millions of people, is worth doing for the process itself. Not just for the fun of it, but especially because you learn a lot during the process. I don't consider learning a waste of time nor a fool somebody that is motivated more by learning than by fame and money.
