Did you read the notes under the slides?

The print was very small. I can't think of a worse way to present one's thoughts.

Edit: well... I guess if I could not control the speed of the slides... that would have been worse.

tl;dr:  

The talk might have been different, but there is nothing of substance in the slides.

There are notes as to what the actual talk covers beneath the slides; some of them are quite substantial.

I haven't even looked at these since it doesn't interest me, but I think posting slides is kind of bizarre: if they're done properly, there shouldn't be anything much of substance in them.

Generally at this point the only reason I post slides at all is for people to leave open and click along while they're watching a video of the talk.
