I am interested in collaborative search and sense-making from back in the day at RENCI when I was looking at InfoMesa, and recent research in my summer class has me thinking about this again. Many aspects of collaborative search and sense-making were captured in the original intent of Wave. I never bought that it was a new form of communication, or that it was revolutionary in that respect. What I still think is that it has some aspects of a platform for collaborative search and sense making. I especially like how it can combine time-shifted asynchronous activities with synchronous activities. What's most compelling is to look at what Wave was doing as an application platform. Collaborative search and knowledge discovery could be a great one for Wave.
