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.
