In addition, you can also get an overall picture of the kinds of questions people are asking, what are the responses people are posting to them, and also, which are the most active topics which are garnering the most interest.
What is most interesting is the way this could be utilized in the organization. Couple of scenarios come to mind ... Would people prefer e-learning to in-class training for a particular topic? Or, do people like the new compensation plan for salespeople? As a standalone tool, though, this might have limited utility, but used in the larger context of social computing tools, this could be quite an interesting tool. A blog, say, could have a reference to questions related to the topic on the blog, as a quick reference to readers, or members of a network could use this tool to find out what people think about a particular topic. Seems interesting, and i possibly, people could find more innovative ways to use this, than any one of us can think of?
