Web 2.0 Early Adaptor Syndrome

Is it possible to be an early adaptor of Web 2.0?
the cat has been out of the bag for some time. The boat has left
the harbor. Elvis has left the building and Web 2.0 is already
talking about Web 3.0.

Web 2.0 strategies and technologies are already widely used online
and appear to be replacing the old static web 1.0 entirely.

You have to know the basics of the Web 2.0 language.
Here's the short list:

Wikis—Collective authoring environments that enable people to
easily populate and edit a Web site based on project or community
needs. Wiki is derived from the Hawaiian term for fast: wikiwiki.

Mash-ups—Applications that combine content from more than
one source to create a new service.

Web logs (or blogs)—Web pages where users can keep a personal
diary or share information with teams, a social network, the
company or the world, helping businesses to drive new viewpoints
and harness the wisdom of crowds.

Here's my favorite. Check out what Mike in the UK is doing with Tags.
He created http://onetag.org.
Tagging—A method of tracking online items that can help you discover
related items and help improve searches and expertise location.

Folksonomy—Again Mike demonstrates the result of tags. (see categories)
The categorization system that emerges from tagging.
