Hi, I had just tried my luck at getting feedback from HN with my new service https://fluxcards.de https://fluxcards.de You are hiring but you say it's completely free for both sides of the deal? How do you plan to monetize on this if I may ask? You focus on real world encounters and usually this means that hitting critical mass is hard to do. Do you market to a certain city or is teaching to a global audience (via Skype for example) a more realistic first step? Lastly would you be interested in cooperating? I have 11k active users (200 daily active) in my Android app and the web version was just released as open beta but I would love to offer my users real teachers via Skype and could see some synergies if you don't intend to tab into flashcards spaced repetition learning.
