I remember when I was writing annual reports which included explanations of the company's technology to the readers. It was some of the best advice I was ever given. It gave me permission not to appear as if I knew what they were talking about, in fact, it was better that I didn't because it forced them to explain it in simpler terms. I noticed as I was with the company longer and began to understand more that I sometimes slipped into a buzzword bingo player's dream. I had to really explain the technology.
Technical writing is even tougher.
