Siviak: A contributor to DEF CON for 14+ years and a geek for over 30, Siviak is considered by some as a trusted (citation needed) authority in the area of Social Engineering, considered by others to be a complete asshole and considered by himself, often.
Siviak has talked with, listened to, pontificated at, entertained, debated, challenged, hoodwinked, and exchanged booze with a great number of us over the years. He is one of the originating voices behind the Lackey Program, undisputed ruler of the Scavenger Hunt, winner of more black badges than any other attendee in history and a proud member of 23b.
