Steve has also been very helpful to the U.S. public service publisher initiative in which I've been active where his advocacy of attention.xml has been pursuasive. I've been convinced that attention metadata are at least as important to its architecture as formal metadata (PBCore in this case) and tagging, which it will also incorporate.
