Bruce Schneier is a cryptographer, security researcher and a fellow at Harvard's Berkman Center, which studies the intersection of society and the internet. Recently, he's taken on the apparently dangerous job of working with The Guardian reporter Glenn Greenwald to sift through thousands of the Snowden documents.  He's also an excellent interview, as this piece from the MIT Tech Review proves.

It's only a few questions, but Schneier explains complicated details of the NSA story clearly and succinctly. Plus he uses awesome metaphors.
