Bernard, Great post. This is a great analysis of the current Web 2.0 business. About your discussion about big business vs. small business and profitable vs. nonprofitable, I have a feeling that there is an essential piece of picture that is losing in the current infrastructure. In normal sense, when a company is growing, its capability of making profit should increase with its growing. However, it is not the case in Web 2.0 industry. It means that there must be a way to help reduce some redundant cost in many Web 2.0 companies that make many of them turning around from nonprofitable to profitable simultaneously. I have some thoughts in my mind though it is not well organized at this moment. Maybe I would share with you later. cheers, and thank you for the great post.
