I’m not doing the tutorial.
I’m sufficiently interested to give it a 30 second video. If that looks interesting I might look at more involved videos about some aspect.
The flow is pretty bare bones though, so if you're used to a text editor and command line tools it'll be pretty familiar.
In your shoes I’d turn around and make a 1 minute video and upload it to YouTube within 20 minutes, showing what your system is and what these data structures look like.
If you have an Apple Mac, the screen recording is built right into QuickTime, just plug your telephone headset into the machine to record some narrative as you go.
Seriously, why launch without showing people what it is? 10 years coding, not willing to spend 5 minutes to record it and show us?
I’m not interested in reading about the deployment process. Really not.
Sell me on what you made.
I think the focus should be meeting the needs of actual customers. And an intro video for people who are still deciding if they will give a chance is not one of those needs by definition.
Right after launch, you want to iterate the product for your actual users. After-launch is not growth phase, is product/market fit phase. Some friction that filters out customers that are not of the early adopter profile might even be desirable.
The only exception is if you do not have enough customers to get feedback from, then you work on this sort of thing.
An important, if subtle, point is that I am not against sales in this early stage, I am all for it. I am against investment in inbound growth-only tactics. Founders doing early sales can both overcome any deficiency in a landing page, learn about what is the best message, and improve their product along the way.
In that sense trying to appeal to people that would potentially use your system sounds like a great idea.
