What is Web 2.0?
The idea of Web 2.0 became notable after the first O’Reilly Media Web 2.0 conference in 2004. During that conference O’Reilly Media brainstormed the concept of Web 2.0 and what it means, here is an 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 |
Quoting from O’Reilly Media:
“Like many important concepts, Web 2.0 doesn’t have a hard boundary, but rather, a gravitational core. You can visualize Web 2.0 as a set of principles and practices that tie together a veritable solar system of sites that demonstrate some or all of those principles, at a varying distance from that core.”
You can find more details about Web 2.0 on O’Reilly Media and Wikipedia.
