That's not true. I have seen great response in many other niche categories like cars, food and success. But of course the largest will be about this new technology. It will take hold because it works and it's a better system. We humans are wired to save time and energy. If we find a new better system then we will adopt that! And clearly by looking at the numbers we can see that people are flocking and these sites are growing fast!

Perhaps the website layout can become better in the future for the ability to be able to find more content. Maybe you could implement some AI and machine learning. The world is moving to many new niches in the world and small tribes. Which is very exciting to see. This is sort of like YouTube 2.0 coming around 10 years after YouTube started. So will take a long time for the site to mature and grow. And competitor websites will come as well!
