But this was a technical presentation at a conference dedicated to the technology in question. A person stumbling across this on HN does not magically make them part of the target audience.
A technical presentation is a still a presentation, as opposed to a reference document. If you want to give someone a block of technical information, you do so in a reference document. You talk in front of a room full of people in order to convince them that this matters enough to bother.
Sure, but I don’t think this is relevant to the comment thread we’re in, which started off by sharing generic advice that mostly applies to TED-style motivational talks or “keynotes” at large conferences etc.
