The Information Today blog has a lot of photos and pretty full coverage.

Commenting on the keynote, Michelle Manafy writes

"I won't go into a lengthy analysis of my first impression of this sprawling and dislocated show (uh, right now I mean physically as the show is so far from the floor--but we'll see if I can draw larger inferences from this comment later). Anyhow, first take from the keynote: something we’ve been saying at EContent for a while now… content is not just that which is produced proactively AS content. This is too narrow a view and will limit the success of any organization. All organizations must view content as, in large part, a byproduct of doing actual work. Keynoter Thomas Stewart from the Harvard Business Review, sees three types of “knowledge”: instilled (yielding smarter products), distilled (knowledge turned into a product), and black box knowledge services (we know a lot about what we do and can help you do it too). I’d extend it to content, quite happily: knowledge collected as a byproduct of your employees’ work or better, as a byproduct of how your customers use your product, services, or even content can help you work better and offer them more."

So knowledge is in the context of work, or at least some form of activity. I'm not sure if the academics at the show accept this, but it makes sense for me.
