'Web 3.0 vs. Web 2.0', has been an ongoing debate for a while. Very obviously, Web 3.0 will be better than Web 2.0, because it will contain all that was present in Web 2.0, along with new concepts, new methodologies, and most importantly, new applications. But then, the transition that Web 2.0 had brought over from Web 1.0 was a significant one. Experts doubted if Web 3.0 would also bring forth similar, or perhaps, better changes. The paragraphs below make an attempt to distinguish between the two.

Web 2.0: User Participation in the World of Information
  • Prior to Web 2.0, the internet was nothing but just a huge number of HTML pages.
  • These HTML pages contained a lot of information, but the user had no involvement in this at all. It was a big library containing a vast number of books, where users could get information from, but contribute nothing.
  • So, if there was any real time problem and somebody had a solution to the same, he could not provide it to the world wide web without having a website of his own. Yes, there were no forums, no bloggers, and of course, no social networking sites. This was when the concept of Web 2.0 came in.
  • Web developers recognized the importance of users and decided to use them to contribute information to this field, hence allowing the amount of information to increase by ten folds.
  • Wiki came into being, and blogger websites became the right place to search for information from specialist users, most importantly the social networking sites.
  • Then, there were the RSS feeds that came into scene. All these were just different ways for the user to contribute information.
  • The web became very intelligent. If you had a problem and type it on the internet Search Engines, you would straight away be directed to the right page where you can find the information or solution.
  • If none of the websites had ever listed the answer to your query, there would be some forum, in which some other user sitting in some other corner of the world would answer your question. Thus, we can safely say that the introduction of Web 2.0 had completely changed the face of the internet.
  • Another point, pages were no more designed in mere HTML code. Languages like PHP, Javascript, Ajax, etc., which allowed to handle dynamic pages, had come into picture.
Web 3.0: User Specific Data
  • Search engines have become more and more specific, that's what is probably the main concentration in this debate.
  • Now, when we surf the internet, the information that is displayed to us for the same search query will be similar to that of another user, who sets in the same on another terminal.
  • Web 3.0 search engines will be more and more user specific and produce precise search results.
  • Search engines of the Web 3.0 era are supposed to be handled in complex queries, queries typed in very much the way we speak. Something typed like "I am shifting over from California, to New Jersey and I am searching for accommodation. I am married and have a son and daughter. What would be the cost of living in NJ?". The search engine will fetch information from different sites and give the right result pages within the fraction of a second.
  • So, one point that is supposed is that the websites will become more and more communicative.
  • Undoubtedly, websites did communicate in the Web 2.0 phase too. A single click on the url on one website could let you travel down all the way to a new website.
  • But, with Web 3.0, they will share information with each other to produce results, which the user precisely wants. Another example of the same is that a single login will allow you to set your status update on Facebook, Twitter, and MySpace together. So much for precise search!
  • Now, what do we mean by user specific data? Concepts like that of iGoogle will become popular and enhanced. The search results for each user will vary.
  • Search engines will keep track of what are the results that a particular user is interested in and produce different search results for different users.
  • Even the advertisements that a user views will be different from what another person views from the same search query. It will be all about artificial intelligence.
  • Web 3.0 applications will be designed such that, though not equally intelligent to the human brain, but ahead from your text editor, with word prediction capability.
  • Some may consider it as a breach into their privacy, but search engines have to say otherwise.
It was a dot com bubble in the fall of 2001, which had brought on the advent of Web 2.0. What had been considered a flaw in the world of internet, was just a new start. Well, whatever has been discussed on the Web 3.0 features are just ideas and concepts. Concepts that the web developers mention. Whether everything will materialize or not, depends on a lot of factors.
