Dion has a great post about some web 2.0 concepts that are popping up in other fields like law, media, and advertising among others. In the post, he states the following about some of the web 2.0 concepts:

But that’s just the beginning.  The interrelated, mutually reinforcing concepts in Web 2.0 like true disintermediation, customer self-service, and harnessing collective intelligence, are resonating with many other industries.  As it turns out, these industries are in the process of being transformed by technology including the relentless collapse of formal central controls, pervasive Web usage, rapid technological change, and more.  These communities seem to be craving a new model for collaboration, relevance, and usefulness.  And Web 2.0 seems to give them both a beacon to rally around and a useful set of practices that can then be used for constructive reinvention.

A good description. As a lot of the recent posts (here, here, and one of my own here) have suggested, this sounds a lot like what is happening with the emerging church. He includes the following list of related movements that are also incorporating some of the web 2.0 concepts (I added Church 2.0).

• Identity 2.0:  Widely covered by numerous periodicals and even at the Web 2.0 Conference, Identity 2.0 is an intriguing concept most identified with Sxip and Dick Hardt (see his amazing OSCON keynote presentation on Identity 2.0 here. It’s worth it.)
• Library 2.0: A very Web 2.0 view of library resources that emphasizes the two-way
  flow information between library users and the library itself.  Lots of
  interesting material, the Web 2.0 Workgroup even has a major Library 2.0 proponent, Stephen Cohen, as a member.  Update: Stephen does not consider himself a “proponent” per se (see comments below.)
  
• Law 2.0: A less-formal movement, Law 2.0 is definitely  on lawyer’s minds and
  has already spawned the first generally accepted Law 2.0 application, WEX.  WEX is a legal wiki encyclopedia at Cornell that is available to anyone and everyone.
• Media 2.0: Newspapers, magazines, and other print media are being revolutionized
  by the Web.  And not only for the better in some cases.  Yet some folks believe in a second coming of media, old and new, known as Media 2.0.
• Advertising 2.0: A Web 2.0 take on participatory, scalable advertising.
  
• Democracy 2.0: A grassroots attempt to repair perceived problems with old-world, representative democracy.  Democracy 2.0 received runner-up grassroots Web 2.0 awards in the Best Web 2.0 Software of 2005 and for good reason.  Lots of interesting ideas and lots of participation.
• Church 2.0: The author of the Church 2.0 site describes it as “Not a movement, but a conversation amongst those disaffected with the largely boomer-driven mega-church movement.” Or, to paraphrase Andew’s series on Church 2.0, a missional, ecclesiastic response to a culture influnced by the ideas of collaboration, participation, and distributed power. 
  

BTW, I submitted this entry using the new performancing plugin for firefox. I think I still need to work some of the kinks out.
