Amazon.com changed the retail world. In the process the company built up so much surplus computing power that it started a dirt cheap "computing in the cloud" business that changed the computing world. This week the company's newest project Public Data Sets on Amazon Web Services began offering more than 1 Terrabyte (1000 GB) of fascinating public data for developers to access on the fly through Amazon's cloud computing service.

We're talking about an annotated collection of all publicly available DNA sequences, including the Human Genome, huge amounts of chemistry data, machine readable encyclopedic entries about millions of different topics and an entire dump of Wikipedia. US Census data, data from the US Department of Transportation and more. It's all accessible by web applications in no time at all. What do you think this is going to change?
