I’m the author and I can answer your question with a clear: no. (Not yet!)
I’m currently in the middle of a learning experiment and wrote the article to get some clarity in my own thinking. One part of the experiment is that I want to learn how to come up with great product ideas. I spend the last few weeks reading everything I can about the topic and the article is the result of this deep dive.
There’s no strategy in the article that I came up with myself. They are all from people who have built something substantial themselves. This is explicitly shown in the image at the beginning. All I’ve done is synthesize their thoughts and put them in a coherent context.
