Web 2.0 | March 28, 2009

Presented by Jiří Brabec

There’s no exact definition. Many definitions emerged at conferences about web 2. A suitable way to describe web2 is using keywords.


Unlike web 1.0, where web pages are built as rigid documents, web 2.0 pages are built to behave more like an application (the Internet is so called a new application platform) for example gmail.com, webmail service.

RIA – rich Internet application (drag-n-drop, flash, interactivity)

No reload of whole page is needed to change its appearance and content. Interactive features such as drag and drop are implemented.

Drag-and-drop– a mechanism that allows a user to select something in one window and drug the selection to another window.

APP (app) – an abbreviation for application

AJAX – asynchronous JavaScript and xml

Decentralization, mashups

Mashups are webs where existing applications are used as a base for additional information (Google maps). This is possible through API.

API – application programming interface, exposure of application functionality to other subjects

Content / new medium

Users participation on content

Community, social websites

Users are connected by unity of their interest (forums of all kinds, facebook, twitter).

Tags/keywords (del.icio.us, digg, linkuj.cz)

Web 2 apps use keywords (tags) to identify and sort content. Users sort out interesting and valuable content themselves.

Content and form separately (xml)

Often you can find exactly the same news on several websites in different design. For example, photos and formatting can be removed. This is useful for mobile devices, rss feeds.

Unique content (sound, video, user comments on goods)

Successful Web 2.0 project must aggregate some unique information updated by users as seen on wikis.

myspace.com, last.fm, ebay.com

Wiki contribution

Collective intelligence can be considered a form of networking enabled first of all by Web 2.0. Collective Intelligence contributes to enhance the social pool of existing knowledge quantitatively and qualitatively.


Many-to-many relationship

Dialogue of two persons: one-to-one

Public speech: one-to-many relationships

Web 2.0: many-to-many relationships – new medium (advanced technology needed)

Web x.0

Many new features of web are emerging. Developers predicts even web 4.0 version.



  1. I am getting closer and closer to understanding what Web 2.0 is. I think that I will get it before I die and by then there will be a beta for Web.?.?

  2. I discovered that Web 2.0 is what I really understand when I hear “the Internet”, because it’s mostly the user created content, creation of social networks and wider range of applications that marks the point when Internet became interesting to me.

  3. What is Web 2.0? I really don´t know… Maybe that now is very easy to use (contribute on) web for all users.

  4. Well, I understand web 2.0 being concept where site provides some applications and sharing.. rather than plain text. I think the website http://digg.com/ is a good example of it.

  5. This topic is really interesting and appreciate the idea of “Web 2.0”. We are using lot of application based on Web 2.0 and most people don’t know, that some tools are part of it. I only guess, how hard would be life for user addicted to social service called Facebook”dot”com without RIA or AJAX :-).

  6. I consider “Web 2.0” concept as good idea, but I think label “Web 2.0” is for the most part just hype. Mainly because so many points of view at this concept, when nobody really knows what exactly the “Web 2.0” is, and also for sake of drawing attention. Common users won’t really find that certain website Web 2.0-compliant, but person or company running that site can claim it as Web 2.0 compatible and lure users into it just because the label.
    In my opinion the idea of interactive web pages is good and it’s the way how will the websites appear in the future. On the contrary sometimes old-fashioned webpages are much more useful than the AJAX based, because they are just information, no more, no less.

  7. And now imagine, how these “web 2.0 pages” would look like on your mobile phone or PDA 🙂
    Usage of new standards and technologies is great, but only to the point when it starts bothering you or slowing your PC down.
    Anyway, its interesting to watch how web is developing in time.

    • I wouldn’t necessarily say Web 2.0 websites are slower. Loading time depends on the technologies used – Flash, Ajax (yep, this takes time to load and it’s one of the classic 2.0 technologies), Images or generally the fact, that the website itself is poorly constructed.

      On the other hand the idea of 2.0 isn’t just that of movable bars and application-like feeling. For me it’s mainly that of connecting the whole web through tags, sites like digg, delicious and this only takes to make a hyperlink or a simple PHP/ASP/… algorithm.

  8. I agree with you. It is necessary to be very cautious when making decision about new technologies. For example, I don´t want my mobile phone to be connected to the Internet although I like the Internet very much.

  9. Hello! I think, I now understand Web 2.0 better than before..but who knows when I will understand it completely.. So, it is acting more like another program on your pc. …interesting…

  10. It is interesting how you can now view the web. The information I have provided a broader view of their own website. I use Google maps and you can not actually know that this is an application that uses the functionality of your Internet connection. There is a large force website. Applications are still developing and creating new phenomena. Such as the social Web Facebook, where people use their personal pages as a means of introducing a permanent search and new friends. When permit applicants (friends) to become your friends, give them access to their site and they also give you view their profile. I look forward to new applications that will become a phenomenon such as FaceBook.
