That used to be a catch phrase in World War II warning people that the enemy could learn valuable intelligence from accidental talking. I am not talking earth shattering information like the New York Times publishing shipping schedules during the Civil War that CSS Alabama's captain read. I am talking things like 'Oh Joe's ship has left again but they were in such a rush he left half his kit home.'
Bloggers have been all over the New York Times because of them exposing the National Security Agency's efforts to intercept terrorist telecommunications. Well the bloggers themselves are leaking like a sieve with specualtions about possible scenarios. I must ask bloggers and posters to blogs to watch what they say, your one little tid-bit might be the final piece of datum the terrorists or rogue nation-state needs to divine some plan the Pentagon has been striving to carry out in secrecy. Be mindful of what is typed, in this era this is more important than idle chat between two people since what is posted can be potentially read by thousands or millions of people.
