Emerging Technology - Discover Magazine - science news articles online technology magazine articles Emerging Technology: "Part of the beauty and power of the original Web lay in its simplicity: Web sites were made up of pages, each of which could contain text and images. Those pages were able to connect to other information on the Web through links. If you were maintaining a Web site about poodles and stumbled across a promising breeder’s home page, you could link to the information on that page by inserting a few simple lines of code. From that point on, your site was connected to that other page, and subsequent visitors to your site could follow that connection with a single mouse click. In some basic sense, those two pages of data were interacting with each other, but the exchange between them was rudimentary.



Now consider how a group of poodle experts might use the Web 2.0. One of them subscribes to a virtual clipping service offered by Google News; she instructs the service to scan thousands of news outlets for any articles that mention the word poodle and to send her an e-mail alert when one of them comes down the wire. One morning, she finds a link to a review of a new book about miniature poodles in her in-box. She follows the link to the original article, and using a standard blogging tool like TypePad or Blogger, she posts a quick summary of the review and links to the Amazon page for the book from her blog.



Within a few hours of her publishing the note about the new book, a service called Technorati scans her Web site and notices that she has added a link to a book listed on Amazon. You can think of Technorati as the Google of the blog world, constantly analyzing the latest blog posts for interesting new developments. One of the features it offers is a frequently updated list of the most talked-about books in the blog world. If Technorati stumbles across another handful of links to that same poodle book within a few hours, the poodle book itself might show up on the hot books list."
