We want to make Finance as cool as programming. I think you pointed out the chief advantage yourself, books sometimes do get boring ( we love books but not everybody has the time or the inclination) . By making this platform we can have access to a much larger user base and just add a little bit of fun to sometimes not too exciting (but very essential) concepts of finance.
We have also thought about adding financial advisors ( WAY into the future), partnering with schools to bring this to teenagers who are about to leave for universities and guiding the audience to tools ( partnering with other companies that provide such tools ) or providing them with same tools.
But in the starting we want to stay focussed on just making educational content.The paradigm is shifting to learning stuff online and we hope to take advantage of that.
