What is Web 2.0

Nowadays, you’ll frequently hear the term Web 2.0 or Web 2.0 apps (applications). It’s a term that’s several years old and refers to the second generation of the web (some say we’re already into Web 3.0 or Web 3D, but that discussion is for another day). If you’re curious, checkout a slideshow I put together last Summer for the Powerful Professional Conference hosted by Johnson County Community College available at http://www.slideshare.net/jbacon/personal-professional-uses-of-web-20-tools. The second slide says most of what you need to know.

In essence, Web 1.0 was a “one way street” (web publishers sent you information they wanted and publishing was restricted to those who knew the language (HTML) and had the tools (HTML editors, servers, access rights). Web 2.0, on the other hand, is participatory. Anyone with web access (a browser) has the ability to publish, contribute, comment and co-author. Tools such as wikis, blogs, and social networking apps are the epitome of Web 2.0. They provide for the “harnessing of collective intelligence” (e.g., we all contribute and the product is better, more accurate and more accessible because it is democratic, self-checked and above all else participatory.

Another way to summarize the shift from Web 1.0 to 2.0 is covered by slides 4-7 of the slideshow at http://www.slideshare.net/anantshri/web20-an-introduction-396686. By the way, http://www.slideshare.net/ site is another example of a Web 2.0 participatory, web-based application.

In upcoming tips, I’ll discuss Web 2.0 apps in more detail. You also have an opportunity to learn more at the upcoming Summer Institute on Distance Learning and instructional Technology (SIDLIT) hosted by the Colleague to Colleague organization and Johnson County Community College on Thursday, July 31 and Friday, August 1, 2008.
