In Fortran one can add two matrices: A=B+C. Try it in C++ (NumPy is better that way, but still this is an extension to a rocky foundation). The amount of freely available high quality math/statistical libraries for Fortran is unmatched. Why in the world would you give up on this just because you can use Google account? Google Payments for settlement?? WTF? Settlement is a bit more then credit card charge or moving money between checking accounts. Google Fiance as a ticker plant?? Yea, right. Even Yahoo provides options data, Google has just basic stock prices. Compare it with BBG that has everything. Build terminal in Web Kit? Why???

Every time I see suggestions like this, I remember minions, rushing from one framework to another - "koonga la mala makuna, koonga!".
