Thoughts and Conclusions
There are two main kinds of use cases I see in Wikistats:
* get lost clicking through stats and engage your mind to new questions.  This kind of brainstorming is not possible with a rigid dashboard.
* find answers to specific questions.  This kind of search is hard on wikistats unless you know where to go.
