Earlier this year (wow, August, time flies!), I wrote that a paper to which I contributed was accepted for the OzChi'06 conference in Sydney. It is titled "An Information Overload Study: Using Design Methods for Understanding" and it describes studies we did in several organisations to find out what is information overload and how it is perceived by employees.
One of the authors and former colleague was in Sydney to present the paper, which received many nice reactions. Here is the link to the paper and the presentation. The paper will also be available through the acm portal.
