I know Daniel, his work is not a ponzi scheme. Because you asked this question in good faith, I'll give you a summary in good faith:

1. The book you linked is just technical content. It teaches you how to use AWS, not how to sell books about using AWS.

2. Unlike the tongue-in-cheek examples of the original post based on minimal success, this book is written based on years of professional experience as a developer building AWS.

3. His content pops up pretty often because people like it.

Of course, if the book was part of a ponzi scheme, then part of that scheme would be having people like me defend it on HN :)

And yet, this is the same guy that peddles a “here’s how to become Twitter famous” course[0].

If you check the testimonials of those who have achieved success, it’s exactly as the article describes. Someone going from 100 to 150 followers going “OMG ITS WORKING!”

I've bought and implemented the strategies in that course. I mean, it does work, at least for those who put the effort in.
