Socratic is a growing site, so there may soon be a day where languages are subjects!
Every new subject that we launch has its own unique and tricky problems. For instance, because a lot of Geometry questions involve graphs, we had to make sure students could add a photo to a question to provide necessary context. That required building a new tool which takes time and people power.
Languages pose a different set of necessary tools, such as new moderator tools, tools for accent marks, etc. so we've got some thinking to do before we would be ready to launch!
