Скопирую сюда пояснения в разнице между абстрактными понятиями между Web:

Web 1.0

    Retrieve information: "The Static Web"
    Like going to a library.

    "That Geocities and Hotmail era was all about read-only content and
    static HTML websites. People preferred navigating the web through
    link directories of Yahoo! and dmoz."

    In web 1.0 we can: Read pages, explore a web site, but can't add
    anything of our own. We can: search the site or the web itself for
    information; sometimes fill out a form.

    Examples: any basic website.

Web 2.0

    Participate: "The Social Web", "Interactive Web"
    Like a workshop, or a party.

    "User-generated content and the read-write web. People are consuming
    as well as contributing information through blogs or sites like
    Flickr, YouTube, Digg, etc. The line dividing a consumer and content
    publisher is increasingly getting blurred in the Web 2.0 era."

    In web 2.0 we can: Interact with a website, not just read it.
    Communicate with other users of a website, or even of different
    websites. Interact with the website itself, and even change it.

    Examples: FaceBook, Wikipedia, Flickr, Youtube, Digg. News sites
    where we can leave comments and choose which kinds of news we want
    to see.

Web 3.0

    Personalize: "The Semantic Web" ("web of meaning")
    Like having a personal web assistant.

    "will be about semantic web (or the meaning of data),
    personalization (e.g. iGoogle), intelligent search and behavioral
    advertising among other things."

    In web 3.0 we will: Search the web in a more intelligent way -- the
    browser will retrieve information for us, and even offer suggestions
    we may not have thought about while searching for information. See
    "our own" web; a different person would see a different web.
    Websites will appear to us according to how we use the web, what we
    look at the most. We don't have to set our preferences, the web and
    our browser will "see" our preferences by what we do.

    Examples: Google and other searches, that give suggestions based on
    what you type. News and information sites, that show articles based
    on what you have already looked at.

То есть, Web 3.0 практически по определению это то, когда за вами
проводится активная слежка, сбор информации. Примером фактически
является только Google (ну возможно мелочь типа Yandex).
