Web 2.0: What Does It Mean?

The concept of Web 2.0 began with a conference brainstorming session between O’Reilly and MediaLive International.
Dale Dougherty, web pioneer and O’Reilly VP, noted that far from having ‘crashed’ (after the dot com bubble), the Web was more important than ever, with exciting new applications and sites popping up with surprising regularity.

The term became notable after the first O’Reilly Media Web 2.0 conference in 2004. These concepts have led to the development and evolution of web-based communities and hosted services, such as social-networking sites, wikis, blogs, and folksonomies.

O’Reilly formulated the 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
