I have been to several presentations which are highly technical in nature (I am a network administrator by trade). These presentations are given by highly knowledgeable people to an audience of "peers" who come from many different companies.
I have seen presentations that last 2 hours and that have 150+ slides. Interestingly enough, I found most of them to be extremely valuable and very engaging. Further, it seemed that to convey the complex topics the quantity of slides was necessary (if no whiteboard for interactive drawing was present).
Given the nature of these presentations, is this too many slides? I can certainly appreciate the need to keep the slides to an absolute minimum when presenting to people like executives or those not necessarily in the same field or level, but are there different rules for presenting technical topics to technical peers?
Thanks for the great podcasts!
