I made my way back over to IDblog and stumbled upon some interesting presentations (Thanks Beth Mazur!).

George Olsen of interaction by design has a nice presentation on IA and User Experience, which spouts some good common-sense-by-example principles.

Another presentation I just read was Is a picture worth a thousand words? by Jean-luc Doumont. A lot of it I skimmed over, but one interesting point I liked was that "nonverbal processing is fast and independent from verbal processing," which is important to remember when designing slideware. Another interesting side point is that abstract drawings are often better communicators than photos.

After reading all of these presentations, you might find this Powerpoint presentation of Tufte's Powerpoint critique.
