Web 2.0 Real Examples

A third wave of innovation is emerging on the Internet. The key element is interaction of users with information and other users on the Internet. This page links to a collection of exhibits that illustrate some of them.

Web 2.0 -- the ubiquitous platform

Platform? What's a platform? Windows is an example of a "platform". Windows is a foundation that supports a wide range of programs used to accomplish all manner of tasks. Computation, writing, business documentation, home theater, video editing, and accessing the Internet are just a few of them.

The Web is quietly becoming a meta-platform -- something more than just another platform. The Web started as a communication utility. It was pretty much passive and one-way -- just a bunch of Web sites that constitute a giant library. Even email is just point-to-point. It's not a collaborative medium. Web 2.0 has become a catalyst for innovations in interactive computing and communication processes.

In this third wave, the Web is becoming a much more open, dynamic and collaborative place. People are creating work groups and social networks with the Web. Developers have built a whole range of new services on the Web (more about that later), and new ones emerge every day. They are blending Flash, HTML, CSS, Javascript and other technology to create seamless and responsive Web interfaces, which they use to implement these new services. Google makes use of one effective blend called Ajax.

Some see PCs being relegated to the role of running browsers to access the Web. Yes, the Web is indifferent about which operating system (or browser) is used. Any old computer -- Windows machines, Apple machines, Linux machines -- is an adequate gateway to the Web. But's easy to get carried away by the hype.

Web 2.0 is not going to replace PCs as we know them. It's going to extend their power further. The revolution behind Web 2.0 is enabling users to influence and interact with the other players on the Internet. The result is better access to the people, organizations and information that they find important.

Programming the Web

Google is the prime example of how the Web is being "programmed". Google also makes their search and mapping APIs (application programming interface) freely available. The APIs enable non-commercial users to easily find and manipulate information on the Web. [NewsGator API]

Google has several Web 2.0 style services based on those APIs, and there are many examples of how others have put them to work.

A Web 2.0 community has been forming over the last several months. This community has the same character as Web 2.0 itself, namely open, networked and interactive. They're involved in things like sustaining the vision, writing standards, resisting hijack attempts, education and providing resources. They're using the Web 2.0 environment to do it.

Social networking

Social networks are a way to represent how individuals and organizations are related and interconnected. Internet social networks can be a "circle of (online) friends" or a mixed network where personal and business contacts are blended within an online community space. The online space is maintained as a Web service.

Sincemost of the examples and figures in the chapter (besides the previoussection) have been examples of absolute positioning, we'realready halfway to an understanding of how it works. Most of whatremain are the details of what happens when absolute positioning isinvoked.

When an element is positioned absolutely, it is completely removedfrom the document flow. It is then positioned with respect to itscontaining block, and its edges are placed using the side-offset Six Apart -- shared space

Web feeds

You can find Web feeds for blogs, news, conversations or any other kind of dynamic (changing) online information. To use a feed, you "poll" it to find out what's new, and if you're interested in an item, you go get it. Web feeds are an important part of Web 2.0. They let people choose what they want to be connected to, and who they want to interact with.

although they are not quite so fuzzy. As you can see from Figure 8-38, it is pretty easy to tell when an element hasgone as far as possible to the right or left.

8.3.2. Applied Behavior

There are a number of interestingconsequences of the above rules, both because of what they say andwhat they don't say. The first thing to discuss is what happensP {margin-top: -1em;}

The problem with this solution arises when the document is viewed inInternet Explorer, which will displaywhat's shown in Figure 7-27. The overlappingtext is not a mistake on Explorer's part -- it's doingexactly as you specified. Basically, there isn't an easy way tocircumvent this problem, although two possible approaches aredetailed in Chapter 11, "CSS in Action".
