Welcome to Web 2.0

tech boxWeb 2.0 is how “techsperts” are describing today’s World Wide Web.

The Web has changed from how it used to be.  In the beginning, Web content was overwhelmingly created by webmasters and corporate experts—people who wrote content and designed websites for Internet users to read.  Internet users, in turn, were mostly passive: reading what was written, learning what was presented to them.

Then came a new wave of Internet applications, applications that encouraged participation, collaboration, creativity on the part of users, and the sharing of information.

Web content today is often user created; Internet users write blogs and upload videos, they share photos and information about themselves, they collaborate to create encyclopedias and to identify the best web resources.  Today, you and I are the experts and we learn from each other.
