well duh, money in of itself doesn't make someone wealthier. Wealth is a reflection of education and social capital. People who are really poor, even if they have high clash flow don't have the social networks built to leverage it. Once you have those connections formed and the insight on how to use it, you can give away all your money because at that point it's trivial to rebuild it.
hey there -- you've developed a really useful tool and I can see myself using this in the future all the time for helping learn languages... BUT I really think you need categorization by language for this to really take off. Otherwise great concept and implementation, hope it takes off!
I'm vouching for kartik too -- I've been in tons of technical convos with him. He's a great guy personally and really thoughtful as a tech guy and is definately someone you want to have on your team.
