I would recommend downloading the .key (Keynote) file from Slideshare and viewing it on your own, if possible. The slide notes are useful, more of the presenter's ideas shared (via http://twitter.com/importantshock/status/4430454006).
I initially thought that was the reason why it was in flash; so slide notes would be visible somehow. Thats not the case though.
Yes. I loathe slide share. Slide share presentations are usually information light. Worse, it presents what should fit on a single page with a couple of flicks of the mouse scroll wheel at most in a hideously inconvenient format. In this case it required literally over a hundred clicks just to get a teaser. Truth be told, I got sick of clicking around click #87 or so and just abandoned it.

Off-topic: anyone else sick of slideshare? Why exactly do they need flash to show a series of images (most of which have images of text)?
