Definition
Web 2.0 is one of those "buzz words" like DHTML that do not have a clear meaning but does refer to a trend or practise that does favor new technologies.
Most often it means:
- New social webservices (see social computing)
- Improved user experience (e.g. AJAX)
- Both of these combined
New web services
According to Tim O'Reilly (2005), Web 2.0 can be defined through examples of how typical web services did evolve. E.g.
| Web 1.0 (past) | Web 2.0 (future) |
|---|---|
| Photo-albums | Flickr-like albums |
| FTP or http-based downloads | BitTorrent |
| mp3.com | Peer-to-peer solutions, like Napster |
| Britannica Online | Wikipedia |
| personal websites | blogging |
| publishing | participation |
| content management systems | wikis |
| directories (taxonomy) | tagging ("folksonomy") |
| stickiness | syndication |
What is common about these example is that “behind the success of the giants born in the Web 1.0 era who have survived to lead the Web 2.0 era appears to be this, that they have embraced the power of the web to harness collective intelligence” (O'Reilly, 2005), in other words Web 2.0 is strongly related to social computing and collective intelligence (the "wisdom of the crowd").
In addition, Web 2.0 is related to enhanced user experience and webservices standards and APIs that allow for more collaboration between machines (data exchange is usually XML-based
Improved user experience
Jared Spool [1] points out the power of APIs: A very good example is Google Maps that allows anyone to overlay data onto any place that Google Maps can show. E.g. here is the place where these very words have been written.
See AJAX
Relation to semantic web
A few years ago, there was a lot of talk about the semantic web. This didn't happen so far ;). So more and more it appears that Web 2.0 means actually going back to the roots of academic Internet in the 80' and very early 90' which was all about communication and exchange. Internet/Web is also (and has been most of the time) about being easy, open and flexible.
