I think its time people stop using shitty slide decks to get their point across.
I, for one, am very grateful to speakers that make the extra effort required to share with a larger group what they have already shared (or are about to share) with a smaller group.
Remember: the author does not owe you anything.
I've been interested in this talk since I saw it announced on Twitter, but prefer to watch/listen rather than go through these slides.
