Let me work
I was at a talk recently in which the speaker mentioned that humans, on average, process a given idea for 6-7 seconds before moving onto the next idea (the speaker specifically talked about "information fragments" getting 6-7 seconds). If people are using technology to communicate or record those ideas, then this brief time becomes very important. If a given technology forces someone to pause for longer than that, then that technology is getting in the way of what they really want to do.
This is at the heart of my comments on my personal toolbox. While the tools might be fun to test and experiment with, when I am using them they had better provide value and not get in the way of what needs to be done.
Interesting. In my experience, most presentations (e.g. PowerPoint) linger on an idea for less than 6 seconds before rushing on to the next bulleted item. Speakers are commonly a bit nervous in front of a crowd and will avoid silences as much as possible. This hurriedness hampers personal understanding as well as group consensus and feedback (if there are sufficient pauses, people [including the speaker] can get a feel for how the ideas are being accepted by those around them). If there is a lack of understanding during a presentation, it can snowball as each sucessive idea is built upon the preceding, misunderstood, ideas... Besides, no one remembers 50 bulleted items - better to focus on 8 and make those more memorable. ...but it is about the message and not the technology of presentation... the technology CAN get in the way (e.g. silly animations that distract rather than illustrate or inform).
