Academia 2.0

Here are some Web 2.0 tools I wish we business academics had:

• A news story exchange - to help alert us to stories relevant to courses we are teaching. I often run into a great story that illustrates, say, advertising but unfortunately I am teaching marketing research that term. You are teaching advertising but spot a nice example of marketing research. How about a platform for sharing these things, and letting people add discussion questions and feedback from how the class reacted?
  
  
• A social network-capable version of EndNote. This would be a personalized citation library that would allow sharing and user tagging and also support comments and dialogs on papers. Maybe something like Facebook's "Wall" application but customized to let people link to other papers, and to allow different levels and types of moderation.
  
  
• A version control system for academic papers. These systems have been in use for software development for years supporting groups who write code together. Despite this, people who write papers together are basically stuck with Word's "Track Changes" function.
  

With all the social network folks running around Silicon Valley these days, is it too much to ask that one, just one of them would turn her or his attention to college professors?
