Web 2.0 defined

Richard McManus points to Wikipedia’s definition of Web 2.0. The definition lists a number of technologies/techniques that make for a 2.0 site.


  • CSS, semantically valid XHTML markup, and microformats
  • Unobtrusive Rich Application techniques (such as AJAX)
  • Syndication of data in RSS/ATOM
  • Aggregation of RSS/ATOM data
  • Clean and meaningful URLs
  • Support posting to a weblog
  • RESTian (preferred) or XML Webservice APIs
  • Some social networking aspects (share your data with friends, etc)


  • The site should not act as a “walled garden” – it should be easy to get data in and out of the system.
  • Users should own their own data on the site
  • Purely web based – most successful web 2.0 sites can be used almost entirely through the browser

What would it take to make our church websites “Web 2.0” sites?
