At DefCon III in 1995, the young crowd of 470 spent their time jamming a local radio station broadcast and playing Hacker Jeopardy at midnight when they couldn't drink at the bar. "Free Kevin" stickers were plastered everywhere protesting the jailing of fugitive hacker Kevin Mitnick, and a 14-year-old ran away from home to attend the event. (I know because I was there.)
At DefCon 19 this year, plenty of the nearly 12,000 attendees had gray hair, most work as security professionals, and some even brought their children. Mitnick was there signing copies of his latest book, "Ghost in the Wires," and posing for photographs, before appearing as a guest on "The Colbert Report" last week.

A community is growing and growing up.
