This computer illiterate strongly agrees with your editorial âÄúTweets roar into historyâÄù from April 21. This mass communication reveals the many contemporaneous aspects of our societyâÄôs psychology and norms. The Library of Congress wisely will maintain a historical record of our culture via the vast stream of mass communication. Its content will continuously change our time and provide historians with a living legend of our people. These tweets, precisely because they are brief, rapid, impulsive and emotional, are correctly characterized by your School of Journalism and professor Giovanna DellâÄôOrto as crucial insights into multiple aspects of our society, âÄúan unprecedented portrait of the zeitgeist,âÄù and certainly a boon to behavioral scientistsâÄô doctoral theses! An interesting note: In WWII, Britain requested its civilians to make note of all conversations in their presence and to forward these to government for analysis by military intelligence agencies. This was an early form of mass communication research. Dr. Leo Shatin, Retired Harvard faculty
