From Tom Murphy we learn that the Irish Stock Exchange sent out a press release, on insider trading of all things, which went out as an attachment rather than ASCII text and that they failed to erase the tracked changes, thus causing great embarrassment.
Obviously this doesn’t happen to flacks sensible enough to use text email. But I think software developers, I’m talking to you Microsoft and Adobe, have a responsibility to make it clear through tip sheets and other means that just because you have deleted something on screen does not mean it is deleted from the electronic copy of the document. For most people this is counter intuitive and needs to be made clear. Blaming the users is never acceptable PR.
