Thanks for reading. The product I chose is not all that important to the article. I believe the value lies in the process related to executing around it, and wanted to share with others.
The article reminds me of get-rich-quick books. "Look at me, I spent relatively little effort and am making XXX amount of money off of it." It's just missing the tagline: "AND YOU CAN TOO!"
As you say, building minimally and only as you need it is good advice. I think the financial snippets are nice and illustrative too. But, the lack of information on market analysis, finding the niche, or information on what the product actually is - all greatly reduce the usefulness of the article.
