I don't necessarily think that this system will be the perfect learning platform for everybody, some people might learn better with other teaching methods, but I certainly think it's worth at least putting it out there and letting people try it. 12 fully general-purpose registers, a flags register, the stack pointer, the instruction pointer, and another register currenty reserved for future uses. I figure it's best to wait until the implementation is relatively stable and there is a mechanism to share your code online so that people don't waste effort or lost interest before the system is ready.
