Actually, submitting the slides is the norm. I just find it odd because when I actually read slides, and then walk the talk after, I notice that the slides alone don't cut it. I'd rather listen to the talk instead.
FYI, the purpose of this slideshow isn't to deliver practical skills. It's to link the big ideas in The Innovator's Dilemna to the modern database market with the intent of illustrating the ongoing relevance of the book.
And maybe to interest a few people enough that they'll go read it.
This is the time I've submitted something here so I've no idea what the norms are. Is slideshare considered bad form?
