Good point. Now we are back to discuss about the valid business model. Making cost effective products and services is one of the value proposition for a new business. But Google and Amazon's contribution are not only to make the services cheaper, they also make the information available easier for online users to retrieve. This is a big step in our information era. Without them, we are still living in a slow and small world. However we need to move further. People know that the web is messy. So we need to organize it to improve the efficiency finding relevant information. So quality should be over quantity. And instead of sorting out from the large amount of information from time to time, we need some way to keep the useful information and share it easily. This is the goal that I'm working on.
