(Setting aside the worthy Cluetrain content for now) @DaveWiner's listicle web presentation software is intriguing. Backed with a cool image, each card carries a bit of text and some web-smart header links. I bet the body text can include links too, which would compound the value of a presentation.
Because the software probably builds on Dave Winer's ever-growing outliner toolkit, I'd also bet that a card might display a section of outline: headline and subheads, capable of unfolding. If that turns out to be true, then you could post a hyperlink-rich web presentation that with revision grows over time into, essentially, all the chapters of a book.
