Applications Outside Education?

I'm a business education teacher and have been recently questioned by administration about the use of 2.0 tools (Google Docs vs Microsoft Word, Excel, Powerpoint, as well as blogging) in my classroom. My reply is that I'm exposing the students to tools that will be used in the workplace, since of course, this is my content area. Now I need your help with my documentation of this:

How are all of these 2.0 tools (any you can think of, and specifically blogging and collaborative documents) being used OUTSIDE of the education world? How is the business world using them? I'm going to do my own research on this, but I highly value your expert input!
