After my return from the Annual Congress of the American Urological Association in San Diego (May 3-8, 2013), I would like to congratulate McKendrick et al [1] and Hanson et al [2] on their recent papers on the impact of Twitter, one of the most common social media, in the medical and non-medical fields. In their elegant communications, both groups of authors stressed the role of the Internet and the Web as new methods of publicizing scientific data. Starting from the use of Twitter during a medical conference, McKendrick et al reported their first experience of using social media as supports for conference organizers, highlighting the use of a Twitter stream as an integral part of the communication structure of a conference on anesthetics. Hanson et al reported a Twitter-based surveillance method for monitoring public health regarding the use and abuse of a psychostimulant drug, emphasizing the potential role of this social media in collecting data for a survey.
