If you don't follow Johnny Long on Twitter, (http://twitter.com/ihackstuff) or via his webpage, (http://johnny.ihackstuff.com/) I would encourage you to check him out. He's a great contributor the the Cyber Security field and also runs a neat organization. Hackers for Charity (HFC) is an organization that, I think, does some good in the world.
