I've been invited to the luncheon preceding the lecture, so I'm doing some quick reading tonight.
Shneiderman's web site seems a bit out of date (it doesn't even mention the new book, for example). I was rather hoping that I'd find a blog there, but no such luck.
Seems like some of what Shneiderman's working on these days regarding visualization of large data sets would be well-suited to the world of YASNS. Visualization is a weakness in most of the systems I've seen. There's all that data there, but it's awfully hard to make sense of except in the simplest of ways. (Hmmm. That needs some teasing out. Maybe tomorrow after his talk.)
