The Machine is Us/Ing Us

Web 1.0 -> Web 2.0

What's the difference between Web 1.0 and Web 2.0?

Web 2.0 is a concept, not a technology... though a number of technologies certainly facilitate Web 2.0. In the original use of the expression by Tim O'Reilly (of O'Reilly Media), for example, he alluded to the use of XML and DHTML. What those acronyms stand for is unimportant. The important thing was that these technologies made it easy for the web to move from "sites" to "applications," with rapidly updated content, authored by anyone with a web browser.

The transformation of the web using these technologies is evident...

Web 1.0
Web 1.x
Web 2.0
Few -> Many
Many -> Everybody
Everybody <-> Everybody
Disorganized
Index/Directory
Folksonomy
Static Content
Rapidly Updated Content
Micro-Content
Clicks
Comments
Collaboration
Hits
Members
Networks

When did Web 2.0 begin?

Of course, long-time web users will protest that those notions were always in place... and that, in fact, the Internet is still not as democratic as it once was. However, few would argue that the newer technologies haven't made participation easier and for more accessible than it used to be.

Social Bookmarking: A del.icio.us Potluck

Social bookmarking involves the use of Web-based tools to save, organize and share bookmarked Web pages and sites. The purpose of this exercise, and the discussion that follows, is to familiarize you with some of the elements of social bookmarking and to explore its educational potential.

1. Follow this link to the del.icio.us account I have created for this course. Log in using the following username (not case sensitive) and password:

username: DMCWeb2.0
password: social3

2. Add bookmarks:

Search within del.icio.us to find a link to any food-related page or Web site: you might look for individual recipes, Web sites with recipe collections, food blogs, Web sites on particular types of cooking.

When you've found something you'd like to bookmark, click on "save this." A new page will open, one that includes spaces to add notes and tags. Add one or two tags; add notes if you wish. Save your bookmark.

Do you have any comments on the educational potential of social bookmarking? Questions? Please post them below.

Learning with Wikis

Most of the class webs at UMWiki are private, but a few are not. First, here is an example class wiki that's not associated with a real class: The example illustrates how instructors may set up a wiki structure to aid and encourage class participation!
