Painful Lesson: Always 'Show and Tell' Your Product Before You Develop It

It's said that amazon asks their product makers to write a press release about the release of the product and work backwards from there. Working backwards has its uses... I recently wanted validation on a product I had already finished developing I thought I needed it so others will too. I put in a lot of time architecting it, designing it with careful UX and UI. When it came time to show and tell through a demo video i couldn't create a simple enough one that explains what it does. So anyway I posted it in some communities and people we just confused and nobody signed up. So I had to abandon the project as there were no takers Cut to about a week back where I had another idea... This time instead of simply developing it further, I jumped straight to see if I can create a explainer video of the product. So with zero expectations about it working I made one without audio or music or even subtitles and posted on reddit. It was just a screen recording of it working on my laptop.
