I own a website service that teaches people a language in a fun way (just one language for now). There are over 50 lessons now and members compete to earn the most points by completing a quiz game.
Our second week in, we have 480 new free members and 10 paying $9/month. Free members currently get access to 8 lessons and our answers community which is much like this site, but simpler. We've had excellent feedback so far. The upgrade offers the ability to save/organize vocabulary and view all lessons without restriction.
We still have some major features to roll out in the coming months as well as iterative improvements to the service. I anticipate the features that are coming are going to be even more useful and engaging for users than what is already there. We definitely have improvements to make though.
My question is this: given our situation, should we give away more for free? What would you do to grow this thing? I have a feeling that if we opened it 100% for free now, it would get a lot more attention... but I don't know if members will pay later.
We are boot-strapped and don't have a lot of money to burn. Revenue is very important to us in the short and long-terms.
Thanks if you can help!
