Real life pinboard-post communication

During a busy office day, I have a lot of simultaneous conversations. I talk to a colleague while I'm waiting on the phone, typing an email on the way to a meeting. That brings along a lot of interruptions. We have to keep it short, abandon a thought or a sentence in the middle, deal with something else and continue the conversation later - that may be in an hour, or in a week.
We only get bits of information from many sides in high frequency. It takes some time to create a big picture from there - and a good memory.
Again: look at the details only, and you see a worthless crap-conversation. Look at the history - and you can learn a lot about a colleague's life.
It's not the "quality" of a conversation that decides about the "quality" of information or education. It's the ability and will of the recipient to work on the big picture.
This tells us where the power in creating understanding is at home. And it can help us to create some rules and guidelines for strong communication.
