The good news is that reddit's growth in the US has slowed, while growth globally has climbed. That's good because US traffic is the most valuable, while overseas traffic, is often effectively worthless, like you can't sell anything to a lot of global traffic. This means reddits operating costs are increasing due to that higher overall site usage, while the rates of monetizable English speaking users is going flat.

I've seen some mention that reddit is embracing non English speaking users to acquire more users and content, but I can tell you as an Internet marketer, this move in general, among all who do it, is like trying to squeeze blood from a turnip, both because they're not valuable to advertisers, and users in places like Japan, Thailand, East Europe have already established usage patterns with LINE, Facebook, WhatsApp, Wykop, etc. The same network effect that keeps people like us stuck to reddit, keeps what little valuable international traffic there is, stuck to whatever they were already using.
