AFAIK most clients don’t automatically tag posts as any language, so almost everything is lumped under undetermined. When I post from voyager I don’t have an option to select the language.
Some former software like kbin automatically tagged language and added hashtags automatically to make posts discoverable by microblog fedi communities. Maybe mbin or piefed are currently using that capability?
But I think the short answer is that the language feature isn’t very practically useful right now, but might be in the future as features are built out/expanded.









Glad they canceled the program when parents said something.
