One's on the way. It's a topic for a different FAQ, certainly. But discussion of the Web's 3.0 iteration has centered on back-end issues such as separating presentation technology and the data, developing and using the so-called semantic Web, and artificial intelligence.
The prospect of separating information from the way it's viewed extends well past making sure that one's Web site is view able in both Firefox and Internet Explorer -- or even in both a computer monitor and a phone screen. As designers know too well, playing catch-up to browsers and devices is a recipe for distraction and frustration. One of the challenges of Web 3.0 will be to come to terms with the ever-expanding universe of devices that seek information from the Internet. Rather than building pages or templates and pondering how to make those behave on whatever devices are around then, those wrestling with Web 3.0 will find themselves working through the ultimate decoupling of the logic, data and presentation of online information.The long-awaited semantic Web, which is actually an expansion of our current Web, aims to make tools as smart about understanding specific information on Web pages as they currently are about knowing what to do when a human clicks on a link. That'll be accomplished by developing a system of machine-readable tags that will differentiate between newer data and older data, between price lists and wish lists, and so forth.
With a robust semantic Web, for instance, one might have an application (an "agent") that can understand not only how to search for information on bobbins, but also how to parse the information to see that per-bobbin prices have dropped by 10% in Southeast Asia this week -- 7% in the past 24 hours alone. If you're a person who cares about your bobbins, you'd probably have your agent configured to alert you that there's a situation in progress. A good agent might even be able to connect the dots between the bobbin crisis and an editorial in yesterday's Bangkok Post advocating a bobbin embargo, or the release of a revolutionary Bobbin 2.0 that'll make all current bobbins obsolete.
Web 1.0 was the initial great rush to populate the Web with pages of information connected by hypertext links. In the later years of the period, many of those pages were driven by databases behind the scenes, but the average person couldn't see much difference.
As high-bandwidth, always-on access became more widely available and Internet usage increased, some sites developed ways of utilizing data from that usage. Some of that data was gathered by the systems themselves, such as Amazon.com Inc.'s "also purchased" feature ("Customers who bought this item also bought..."). A great deal was contributed directly by users, generally in the form of short reviews, comments or suggestions. Though relatively few users participated heavily in such collaboration, the ability to collaborate encouraged the development of a remarkable "group wisdom" on such sites.
Over time, collaboration moved to the heart of the Web 2.0 experience. Sites such as those of Craigslist Inc., eBay Inc. and MySpace.com Inc. provide three very different experiences, but all are entirely predicated on user contributions and interactions between those users.
Meanwhile, community-centric sites such as Slashdot and Digg relied on readers to contribute links (usually to news stories) that might be of interest to the community, to describe and comment on the contributions, and to moderate (and thus provide first-line filtering of) other users' comments. This gathering function has become a de facto answer to Web 1.0's information-dispensing model -- rather than consuming the news as presented under a single brand (such as USA Today or The New York Times), those using a Web 2.0 news-gathering model tend to check community-driven aggregation sites for pointers to specific stories on the news sites. A few news-gathering sites dispense with the human element altogether, relying on robots to parse and numerically weighting the importance of news stories as they happen.

Everyone uses web 2.0 in our generation, but mainly teenagers, young adults and buisness men/women.
The term Web 2.0 was coined in 1999 by Darcy DiNucci, a consultant on electronic information design in her article “Fragmented Future” and became closely associated with Tim O’Reilly who used it in a Media Web 2.0 conference in 2004 to describe the future, as he saw it, of the World Wide Web. T
he term, seen by many as misleading, stuck. Tim Berners-Lee, the inventor of the web, labeled the term “a piece of jargon.”
Although the term Web 2.0 implies a new or updated version of the World Wide Web this couldn’t be further from the truth.
There were, and have not been, any technical updates to the Web.
Web 2.0 is the term given to describe a second generation of the World Wide Web that is focused on the ability for people to collaborate and share information online.
Web 2.0 basically refers to the transition from static HTML Web pages to a more dynamic Web that is more organized and is based on serving Web applications to users.
Other improved functionality of Web 2.0 includes open communication with an emphasis on Web-based communities of users, and more open sharing of information.
Over time Web 2.0 has been used more as a marketing term than a computer-science-based term. B
logs, wikis, and Web services are all seen as components of Web 2.0.
