The document discusses how starting an online business is fundamentally different than extending an existing offline business online. It notes that the internet allows for a 24/7 sales cycle, national/international reach, data collection, and easy promotion by customers. To succeed online requires treating it as a separate business by studying the new marketplace, hiring the right people, constantly testing ideas, and staying focused. The key message is that existing businesses should approach going online like starting a new business from scratch rather than just an extension of their current one.
