THE EDITOR'S CORNER
Volume 51 : Number 5 : Page 257 : May 2017
Like almost every U.S. orthodontist, JCO maintains a Facebook page as one means of connecting with its customer base—in your case, patients; in ours, readers. The format doesn’t necessarily lend itself to dispensing clinical information, although we have recently begun posting helpful videos related to our published Pearls. We tend to get the most likes and shares from our monthly profiles of finalists for the Eugene L. Gottlieb JCO Student of the Year Award (the most recent winner was announced in the March 2017 issue), no doubt because of these students’ extended networks of relatives and colleagues. But the 50th-anniversary year of the journal has brought us an opportunity for a new and unique Facebook venture.
