Brad Fitzpatrick is president of LiveJournal.com, a social discovery Web site where over 1.5 million users post diary entries they want to share with friends. Although members post extremely sensitive information in their journals -- everything from their plans to commit suicide or sabotage their boss to their latest sexual adventures -- Fitzpatrick admits that security on his site isn't a priority. . . .
