Haha ... nope, why don't YOU create it? Web 3.0, like Web 2.0, is just a group of ideas and what that will "look like" is still anybodies guess. Type it into wikipedia and you will be able to get some projections and ideas about what it may become, but no one really knows, and it really is in our hands. Web 2.0 is, to generalize greatly, sites that are more focused on user-created and controlled content, interactive experiences, etc ..
There is not a specific definition for web2.0 if im not wrong. Many people use the term web2.0 when talking of designing aswell which includes a bright design with reflection, rounded borders and bright colours.. Just my 2 cents. Never heard of Web3.0
I believe the world need web 2.1 at first ... web 2.9rc3 ... and only then web 3.0 =) Sorry. Just joking Web 3.0 is fiction. This is only high-flown word to make high-flown news
I hate to burst your bubble, but there is no such thing as Web 2.0 or 3.0 - it's just marketing hyperbole. The Web, like everything else, evolves and changes over time, especially as designers and developers learn how to make sites that are more usable and accessible to everyone regardless of location, language, and ability (or the lack thereof).
There is probably some "marketing" behind the idea of web 2.0 but I think there is a difference between web 1.0 and 2.0. I think 2.0 is just nomenclature. You could just call it modern web design and content generation. When you visit a site that looks like it was built in straight html sometimes in the 90s with no user added content I would call that 1.0. When a site looks "modern", has user generated content, and is more community based then I feel it is web 2.0. I starting building websites again about 2 years ago after a 8 year break. My first efforts were definitely not web 2.0. The web evolved a lot in those 8 years and now my recent efforts reflect that. Now I rarely create a site that doesn't allow for user generated content. I don't use "FrontPage" or anything like that to develop a site but use the powerful content management systems that are freely available such as Joomla or Drupal. Then for that final touch, I usually use a logo that has a "reflection" because that seems to be the rage these days. Anyway, that is web 2.0 how I see it. As far as web 3.0, I have never heard of it.
Even though he is looking at the social aspect of the Web's evolution (not that I can fault him for it - it's one of the things that helped bring the industry back from the brink after the dot com bust). There's much more than social networking (or engineering as I like to call it) to the latest trend in Web design though. Web standards for the most part really came into its own no thanks to the likes of Jeffrey Zeldman, Eric Meyer, Dave Shea, Molly Holschzlag, Cameron Moll and other top designers. The use of increased white space (a real usability plus if you ask me) and moving away from designs that crammed as much content into a limited space as possible led to the current "Web 2.0" look and feel which many people tend to associate with modern design practices. The great thing though, if you ask me, is that there's enough room for the standardistas and the new age designers to happily co-exist.
All marketing rubbish, web 2.0 was just a name coined for a type of website that was suppose to "revolutionise" the internet as it would be heavily user contribution based rather than information/ pages created by one person/ company and served up in a read only format to the masses. Web 3.0 is basically exactly the same, the next "step" on the internet as users change what they want and hardware enables it to be possible. Many of the concepts are being able to access the content of the web (not necessarily pages) in more places using more devices - have your fridge being able to access a receipy API for you to build your shopping list and send it to your supermarket to have it delivered but also references your online calendar to know when you will be available for the delivery. The prediction is also it will become much more graphics based - some have flagged the likes of Second Life as an example of a web 3.0 where you have an online 3d store that can sell your products and people can almost literally use them before buying.
What Astarothsolutions said is basically 100% correct on the exstimated prediction of what it will be, another thing also that its for people that dont understand web2.0 ( i didnt say that i read it somewhere LOL ) my 10 pennies
