Nova Spivack‘s definition of Web 3.0 as being a decade (2010-2020) of web technologies is, I think, probably a better one than something nebulous and open to interpretation – such as Web 2.0, which Tim O’Reilly defined but which most people just interpret for themselves. Nova defines Web 3.0 as being the set of technologies we’ll see on the Web from the decade 2010-2020. (Shouldn’t that be 2010-2019?) And it’ll bring lots of fascinating tools and platforms.

On the other hand, if it’s just whatever technology we’re currently using online in a given decade, then why “version” the web?

Well, I’ve been using public networks since the 80s, so I don’t really think of “versions” of the Web unless forced to. But it is easier to say “Web 3.0” instead of “the Web technologies that were introduced from 2010 to 2020.” It also means that a version number won’t be appropriated to define some specific technology, or misinterpreted like Web 2.0 has been.

Web 2.0 is simultaneously “the social Web” and applications using AJAX or other backends and RIA (Rich Internet Application) front ends. But it is other things to other people now.

Web 3.0, according to Nova’s diagram, includes mashups (such as Yahoo Pipes, which I love), Widgets (which I don’t use), Semantic Search, Semantic Databases, and more.

This does mean that I have to stop calling the Semantic Web “Web 3.0”. As Nova points out, they are not the same. The Semantic Web will also no doubt play a big role in Web 4.0 (2020-2030), but most of the tools and platforms are expected to be released next decade.

If you’re interested in reading more, go check out Nova’s article and see his great graph of Web 3.0 and other technologies plotted on a timeline.

What I see, personally, is a larger integration of the Mobile Web (Mobile 2.0) with the “regular” Web – both in terms of tools and platforms.
