An interesting article by Tim O’Reilly that aims to [clarify what Web 2.0](http://www.oreillynet.com/pub/a/oreilly/tim/news/2005/09/30/what-is-web-20.html) is.

In our initial brainstorming, we formulated our sense of Web 2.0 by example:

**Web 1.0 **Web 2.0
DoubleClick Google AdSense
Ofoto Flickr
Akamai BitTorrent
mp3.com Napster
Britannica Online Wikipedia
personal websites blogging
evite upcoming.org and EVDB
domain name speculation search engine optimization
page views cost per click
screen scraping web services
publishing participation
content management systems wikis
directories (taxonomy) tagging (“folksonomy”)
stickiness syndication

But, this could all be old news as the NYTimes report the emergence of Web 3.0.

Their [computer scientists and a growing collection of start-up companies] goal is to add a layer of meaning on top of the existing Web that would make it less of a catalog and more of a guide — and even provide the foundation for systems that can reason in a human fashion.

At last the boffins have caught up with us journalists. We have been talking about Journalism 3.0 for nearly five years.

In an article in 2005 Dan Gillmor thought we where closer to web 3.0 than we thought.

The first big shift – to what I prefer to consider version 2 – came when the web became more of a read-write system. This was a huge change, and it’s still in progress

But it was 2002 when Dan saw a future for journalism which he called web 3.0

Until very recently, modern journalism was mostly a lecture — journalism organizations told you what the news was, and you either bought it or you didn’t. Today’s professional journalist needs to understand, and capture, the fact that our readers/listeners/viewers know more than we do. That’s not a threat. It’s an opportunity. Digital collaboration and communication tools are helping us all create a new kind of journalism, something resembling a seminar or conversation. The tools range from e-mail to weblogs to peer-to-peer, and they all add up to something genuinely new in news. Don’t ask about the business model, however; no one knows what it is.

He predicted that there would be a major news event and new technology meant that

“…there will be 400 photos taken of it in the first minute by cam-equipped cellphones. Those 400 photos will make their way to news organizations and to individuals and we will have 400 visual perspectives of that event from the ‘former audience.'”
