Great question. From a consumer only perspective: I always like where there is an easy method to review the presentation again. Like a link to a video of it.

Great question. From a consumer only perspective: I always like where there is an easy method to review the presentation again. Like a link to a video of it. Also a link to read more detail. Hate when text is presented to fast. Hate when talker is too fast. This is a common problem with not experienced. Typically showing me code is a waste as I cannot mentally process that level of information and still hear you. I find it very useful, and this should be obvious, when the talk matches the visual. I like to use one to complement the other, not provide an overload of information.
