Joe, my point wasn't that people are literally applying the term DRY to their human to human communications. My point was that they unintentionally do it. I'll see time and time again a blogger or writer or speaker stuck. And one of the reasons they are stuck is that they feel they are out of material. What they can say has either been said by themselves before or someone else.
And I feel especially us programmers who are so used to not repeating ourselves are especially victim to this.
So my point is there is a ton of treasure in polishing and reiterating wisdom you or other have shared before, since the time or times you tell it in your own way may very well reach an entirely new audience (or old audience that really needs to hear it again).
