People disagree with this, but anyone who shipped something online 15-20 years ago knows this.
This is simply because the market didn't used to be so saturated and distribution was straightforward and building was still the barrier.
At one point I knew almost every single cool website that launched, simply because not many launched cool websites and word quickly got around. The same goes for software or apps.
Building used to be a lot harder, which is why we rewarded it with easier distribution.
Now it is flipped, building is easy, distribution is hard (due to saturation, higher expectations & pay to play mechanics)
"Build it and they will come" no longer applies online. At least not to the degree that it used to.
