the International Stamp Exchange

You know, when Armand Rousso opened or rather launched the first online eCommerce company, many people told him that the medium wouldn’t work. Now he must be thinking why he didn’t patent the processes used by the International Stamp Exchange (the world’s first e-com venture started by him). This proves, beyond doubt, that one must truly listen only to his heart and not get deterred when others doubt his innovative concepts..!! Right?
