I'm not sure it's entirely similar to what you mentioned, but I too remember the sensation of focus, that I'm struggling to get these days. I started to realize this after the web2.0 era.. thinking that ajax infused web apps would allow for better communication and thinking but it mostly unleashed noise, and whenever I run into old, limited forms of communication, i get the sense of value and focus back. Only the things that matter gets to your attention, and it reaches deeper and faster.
