I'm not sure you need to use the sentence structure that you are trying to use to get your point across. Why not simply use, "Most content on reddit.com is in English." (Or, "all content" - I don't know if there is non-English content.)
The United States of America is an English literate country.
Reddit is a an English literate site.
Sina Weibo is a Simplified Chinese literate site.
I think you would still use the -speaking suffix. Even though we don't actually speak on web sites, the term generalizes to refer to any medium. After all, in an X-speaking country, we expect most books and periodicals also to be written in language X.
The only reason we might need a different term for writing is if we were in a place where the language used in writing differed from the spoken language, so we would have to distinguish them. I'm not sure there are such places, although there are places where the language used in casual settings is different from that used in more formal settings. There are also places where there are multiple writing systems (Japanese, for instance), and one might need to indicate which one is used.
