Don't know if any one here has posted something like this but how about any popular language learning app. I live in China and know only a fraction of the language. I'm too lazy or busy at times to study but I really do want to pick up on it more. I can imagine it being integrated into Steem and rewarding you to learn any language. It'll give you an incentive to put in time and effort to learning the language you desire. In the end you prosper and have become fluent in a new language, a notable accomplishment.
