On a more serious note, I'd be super interested to know how high the percentage reddit users who don't speak any English is. And how high it could grow in the future. I'd wager that most of the people that hang around r/de and r/france are also members of English-speaking subs (even if passive). That's because the interesting thing about reddit is that you have all these niche communities of your interests that you could join. But if you fragment these niches further down by language, you end up with communities that are too small to be interesting. E.g. r/Elektroautos/ just does not have enough content, compared to r/electricvehicles/
