What is Web 2.0? January 1999, Darcy DiNucci: “The Web we know now, which loads into a browser window in essentially static screenfuls, is only an embryo of the Web to come. […] The Web will be understood not as screenfuls of text and graphics but as a transport mechanism, […] through which interactivity happens. It will [...] appear on your computer screen, [...] your cell phone [...] hand-held game machines [...] maybe even your microwave oven.
