I came across a fantastic and entertaining talk by Eben Moglen. He is a Professor of Law and Legal History at Columbia University, and founder, Director-Counsel and Chairman of the Software Freedom Law Center. Apparently he started as a software engineer, which explains why he is so comfortable going into technical details of software and hardware.

He explains how Facebook is offering next to nothing in exchange of privacy and how he thinks everybody should have her own wall wart running a web server so that we keep our data to ourselves.
