Matt Watchinski of SourceFire gave a presentation on 6 Nov 2009 at DojoCon 2009 wherein an opening slide (the "fluff" slide, he called it) depicted two women sitting back to back wearing nothing but t-shirts and thong underwear. He was asked at lunch why he thought it a good idea to include that image. He listed a number of reasons, such as: As usual, the assumptions are that everyone involved enjoys looking at potentially attractive women, scantily clad women, women exist to be stared at, and of course that sexual content is appropriate in a professional conference setting.
