Isn't this a problem of "network effects"? As the network grows, the quality lowers? To remain high quality you need strong filters which ultimately shrinks the network.

Substack is gonna be exposed to a similar problem as medium, and they may be able to solve it, but I don't expect so, because they aren't building a "magazine" but a "publishing platform".
