Symbol of the type of reader who made Time magazine call us the jitterbugs of the pulp magazine field in its article on the NYCon I. The expression led off an allegedly typical letter they quoted, commenting on TWS; indignant fans held it to be an invention of the reporter who wrote up the NYCon, for a long time. Martin Alger finally tracked it down in "The Reader Speaks", TWS' letter column, for August 1939.

(Time) - Symbol of the type of reader who made Time magazine call us the jitterbugs of the pulp magazine field. The expression appears in an allegedly typical letter which they quoted, commenting on TWS; probably it was an invention of the reporter who wrote up the New York World Convention. It has become a gag line in fandom.
