I have been thinking of similar things, which is why I decided to take the risky road and know that if I fail at least I did it in pursuit of something worthwhile.

I am working on a somewhat educational software, Ajaxified and all that, which I believe could make a difference while being possibly profitable (perhaps not high-margin enough to attract VC investment, but if it can provide a stable income I'd work on it with no complaints). It seems to me that traditional teaching institutions, or the general public, seems grossly uninformed about the theory behind it -- which to me seems to be the only, theoretically and experimentally, universally solid method that guarantees learning results, as far as my exposure to relevant material is concerned.

I assume there lacks satisfactory implementations because those who understand the theory don't bother making a product that is accessible to all; I am simply tired of waiting.

I believe a good number of participants here are also not exactly short on the starting capital. The difference is in the mentorship and extended reach.

One reason why web-based educational software is absolutely necessary, in terms of making a difference, is that you can connect with users anywhere in the globe. Kids who use cheap laptops. Once you guarantee your learning method is good, you're on track.

At least I believe so :)
