I tried to find the meaning of Web 3.0 on wiki. And wiki ... : "future of WWW". Not even 2 years back, I heard the same for Web 2.0. Web 2.0 defined by O'Reilly in this fashion:
Web 1.0 Web 2.0
DoubleClick --> Google AdSense
Ofoto --> Flickr
Akamai --> BitTorrent
mp3.com --> Napster
Britannica Online --> Wikipedia
personal websites --> blogging
evite --> upcoming.org and EVDB
domain name speculation --> search engine optimization
page views --> cost per click
screen scraping --> web services
publishing --> participation
content management systems --> wikis
directories (taxonomy) --> tagging ("folksonomy")
stickiness --> syndication
Sounds quite fine. We almost moved on Web 2.0. How about Web 3.0?
Web 3.0 talks of Data(Content) which is THE important, managing data in a RIA(Rich Internet Application) format and many more which is not clear in my mind.
One of my friend, Ankur passed this link : http://www.verveearth.com/landing/. Is this web 3.0 ? Sounds like.
This link will show you all blogspot blog on Google earth. Data moved from Database into representation format, offcourse RICH. And this is what written about application "VerveEarth is mapping the internet's content onto a global map. Discover the voices of your world. Get started by exploring the map or registering to add your blog." And Yes,this is RIA(according to me). Internet content is enormous, scattered in a useless format. Gathering those information, giving a useful shape and presenting it on a RICH view is what I thing Web 3.0 is.
