Not all exponential growth is the same: x^2 and x^1.01 are both exponential. I’m asking you for evidence that the exponent is higher for niche isolated networks

Not all exponential growth is the same: x^2 and x^1.01 are both exponential. I’m asking you for evidence that the exponent is higher for niche isolated networks than it is for communities on platforms with algorithmic promotion to a massive existing userbase.
