Remember when you were a child and you sat in a circle and one person whispered something into the ear of the child next to them and this continued around the circle until the message came back to the original speaker? Was the message ever the same? Rarely!
This is what happens sometimes when we issue a press release. Journalists may trim your press release to a few sentences. With twitter, well-intentioned followers will reinterpret your release into less than 140 characters, potentially causing the message to be garbled and lose its full meaning.
