One of he areas that is the most significant whirlwind of change is the rate of information creation that we are living thru. Andreas Weigend is a sort of tornado hunter of the information whirlwind - he is the former Chief Scientist at Amazon.com and an expert in data mining and computational marketing. He currently teaches the graduate course Data Mining and Electronic Commerce at Stanford University.
His post The Social Data Revolution(s) is sensational:
In 2009, more data will be generated by individuals than in the entire history of mankind through 2008. Information overload is more serious than ever.
The second data revolution brought about a new dimension to data creation: users started to actively contribute explicit data such as information about themselves, their friends, or about the items they purchased. These data went far beyond the click-and-search data that characterized the first decade of the web.
In the last few years, users have gone a lot further than contributing metadata to movies and music: in fact, they have taken center stage. The center of the universe has shifted from e-business to me-business. Customers are also starting to discover and interact with each other. Knowing that they are not alone has shifted the balance of power from companies back to consumers. And they have begun to demand transparency. Customers are beginning to have a voice. They are realizing that the data they voluntarily contribute can help them and others with making decisions, providing true value. In turn, they want to be treated fairly as individuals by the companies they pay attention and money to.
