Found this video when I was doing some search on you tube. The video is almost three years old but I think it is is still relevant to watch. You can hear Rajan Anand talk about the exponential way in which the web is growing and the B2C/ B2B opportunities it is throwing at potential entrepreneurs.
If you are a person who is looking forward to start a business based on web/ cloud/ social networking, this is a must watch video!
