Con talks should not be presentations. They should be conversations. If I just wanted the content I can watch the replay on YouTube or you could have saved us all a lot of time by writing a whitepaper.
Cons are not all about the talks. I love a good CTF. I love going out for drinks and just bullshitting with like minded security professionals for a couple hours. I love meeting new people in the field. I love when people do dumb shit like hack the menu at the restaurant that was dumb enough to use an iPad for their menu in a town full of hackers.
An hour talk is the format for giving someone a high level introduction to a new topic or technique or technology that they have little to no experience with. It's deeper than a blog post, but lighter than a white paper. If you really want to turn a newbie in a reverse engineer, or something similar in scope, that depth probably should be a one week bootcamp, or a structured multi-week course (online or in class room).
