I've added three presentations to the "Writings, Presentations" list on the left:  "Public Service Media in a 'My Time' World" from the 2005 Integrated Media Association meeting in San Francisco (also see Stephen Hill's companion presentation, "The Public Service Publisher Initiative"), "PBCore: The Public Broadcasting Metadata Dictionary" from the 2005 PBS Technology Conference in Las Vegas, and "Scenarios for the Future of Public Broadcasting" from the May 2005 Channeling Public Interest Media" conference, also in San Francisco.  --Dennis
