Matthew Hurst has clustered reviews of the Nokia Lumia 900.
His blog post is an image of the cluster at a point in time so you will have to go to http://d8taplex.com/track/microsoft-widescreen.html to interact with the cluster.
What would you add to this cluster to make it more useful? Such as sub-clustering strictly reviews of the Nokia Lumia 900 or perhaps clustering based on the mentioning of other phones for comparison?
Other navigation?
You have the subject (what is being buzzed about) and you have a relative measure of the “buzz.” How do we take advantage of that “buzz?”
Navigating to a place is great fun but most people expect something at the end of the journey.
What does your topic map enable at the end of a journey?
