  3. Of course not phones! I mean, "The President's Analyst" ;) But from a professional, and WWII hero: > 17. The greatest material curse to the profession, despite all its advantages, is undoubtedly the telephone. It is a constant source of temptation to slackness. And even if you do not use it carelessly yourself, the other fellow, very often will, so in any case, warn him. Always act on the principle that every conver…

And if so, I request that they be disconnected. And if the host declines, I may leave -- or at least say nothing consequential. My wife's phone is on 24/7 and almost always within easy reach. So I never say anything consequential, unless it's been moved to t…

  9. I contacted Google about this issue in November of 2008 - I only received an automated response. (Matthijs mentioned that was why he posted the previous post[1] on the topic prematurely) Perhaps with the increasing awareness of this issue, Google will be forced to act.
