I think it does exactly what Sean is teaching us – massive value for free to build trust and perception of being an expert.
To my mind, it’s got more actionable value than at least two regular WSO offers (content creation, video creation, maybe SEO as well).
Doing the same in our respective niches plus probably a call to action subscription option (something Charles deliberately avoids, his main target market is people spending $3k per month upwards on SEO services) would be a good way to go.
And anyone procrastinating on creating content can learn a lot as well 🙂
There’s a lot in the post that’s unsaid – the assumption is that you also know the subject at least a bit and it fits well with Sean’s “I can’t tell you everything in just one audio” outlook.
