As a self-professed psuedopsycho presentation snob, I hate that people find value in slide decks. So maybe that’s really it: I don’t hate SlideShare itself, I hate the fact that there’s demand for something like SlideShare.
I've had the same experience as Ron. People insist on getting my slides but those who've seen me present know that the slides are often unrelated to the talk. And certainly not representative of my talk. And so often, it's the conference organizers who are anxious to post my slides... FOR THE PEOPLE WHO DIDN'T ATTEND!
Why in the world??
Want the slides? Attend the presentation first!
