I read the post. The title is correct, but the article itself doesn't follow, because the major theme is about caring. Caring about something enough to build it out is important. But "caring" does not equal "customer demand".

I'll be presumptuous and suggest a better theme:

"Success begins and ends with the value proposition--if customers want it bad enough, you have a potential path to build something. But...don't build it if you don't care about it."
