And will you find a way to win many teaching people to read? If you did, you'd be a God, ok no. But wouldn't you need more people working with you to make all those learning apps?

Which are the language courses with more contributors offers?

What do you think about Esperanto as a bridge language (learn Esperanto for Spanish speakers and then all the languages you want, from Esperanto)? By the way, do you think you'll be adding in the future Esperanto for Spanish (I'm a native Spanish speaker, from Argentina I thank you for creating that amazing app :')

Hmm... when thing are stable on duolingo, wouldn't it be nice to allow users to create a conlang and make their own tree, so people could visit my profile, see my conlangs and give them a try?
