This is great advice and it is fantastic because it is specific and actionable.

I would love to see one tailored for validating consumer products rather than B2B ones.

A good amount of this is definitely applicable to validating for consumers though.

I especially like the section recommending that a product and the problem it solves be described fully in text before any code is written.

Agree, so much of the advice on HN is for B2B. I get that the success rate for B2B is higher, but some B2C advice would be very welcome.
