For all of my comments and posts, I have been selecting the “English” tag (side note, it would be fantastic if I could configure a default. Better yet, it would be nice if a community could set a default, and I default to that). Is this good practice? Or is this having some unintended side effect that I am not aware of? I’m guessing that it just makes filtering easier for people that filter by a language so that they only see posts of that language.
I believe you can select multiple languages. It’s to allow you to filter the feed down to only content in your preferred language. The default is undetermined so that’s what most of the posts are in.
