I don’t really want to get ahead of myself here… we’ll have to see how korean goes. I suspect once I have things set up for two languages, it should be relatively simple to expand to a few more if they’re straightforward, like romance languages. German would be very easy; Spanish is the most attractive one, but I’d have to handle dialects, which may (or may not) pose complications.
But, we’ll really have to see how well the platform is performing for Japanese. If we can’t show a model which is really attractive and growing for Japanese learners than chasing additional languages is fruitless. We very well may just focus on Korean and Japanese for a while.
I probably wouldn’t even be doing Korean right now if it weren’t for the fact I am living here 
. But I do think being able to do a language I’m focused on and can do in person outreach for is beneficial.
