Web 4.0?
Internet’s growing up. Since the “Web 1.0”, a static Web only for readers; the Web quality is bettering. The changes into the “Internet language” (html and his extensions like XHTML, CSS, flash or JavaScript and techniques like Ajax) have became Internet in the “Web 2.0”, allowing the user to write in the web. The Web 2.0 is blogs, videos (youtube) and other social networks (facebook, linkedin, flickr, lastfm, Google maps, etc.). The new “Web 3.0” (as know as Semantic Web) isn’t real yet, the third internet version includes metadata on the web pages linking contents.
Some talk about the Web 4.0 as a mobile web, the iPhone is a example. But I think that is the Web 5.0; the Web 4.0 is nearer than they think. The Web 4.0 is a Web 2.0 extension. The service developed to create the Web 2.0, now, they will be used to earn money by users.
The first steps on this way are LastFm (http://blog.last.fm/2008/07/09/calling-all-musicians) or the Getty Collection on Flickr (http://blog.flickr.net/en/2008/07/08/the-flickr-collection-on-getty-images/).
