Part 1: Visual Definitions of Web2.0
“Web2.0″ pronounced “Web Two point Oh”: can be used as an adjective, noun, verb, adverb.
Stop right here, remember, I am not a techie, I will leave the written definition to the experts.

The problem is when I try to pass these definitions on with other nontechies, like other teachers, administrators, and parents at my school, I have had an extremely difficult time trying to articulate the essences. So I have put together a collection of visual diagrams, webs, charts, tables, and time lines that may assist you in quickly absorbing some of the essence.
