Product hype might be hard with developer/tech types of tools. Devs have very good BS radar and "hype" is sometimes all there is in a lot of content. I see and hear a lot of the "build in public" being promoted as the way to do things with the "build an audience" mantra.
There is a huge hurdle to produce good video content, it takes a lot of time to record, edit and publish quality videos. Publishing quality videos can help get traction/views/subscribers but that doesn't mean it will translate into paying customers either. Do people really want to watch software developers code or talk about it? There has to be other ways to market a product.
