From the post:
We are about to deploy an experimental system for searching through CiteSeer data. The system, Querium, is designed to support collaborative, session-based search. This means that it will keep track of your searches, help you make sense of what you’ve already seen, and help you to collaborate with your colleagues. The short video shown below (recorded on a slightly older version of the system) will give you a hint about what it’s like to use Querium.

Could be your opportunity to help shape the future of searching! Not to mention being a window into potentials for collaborative topic map authoring!
