Yes. I get that. But, why is that the same number of people search for a specific term everyday? Is the aggregate demand so predictable? Don't you find that weird?
I don't find it weird. It's basically the smoothing effect of very large numbers which is what statistical analyses depend upon. If you wrote two new very different apps, then you may find different "steady state numbers". The more niche the app the smaller the numbers and the more "hair on fire" the target need the larger the numbers. It's actually a rather well known dynamic in marketing. That's why they use certain words to capture attention.
