Legends of the Ancient Web
An absolutely fantastic talk (as always) from Maciej, this time looking at the history of radio and its parallels with the internet (something that Tom Standage touched on his book, Writing On The Wall).

It is hard to accept that good people, working on technology that benefits so many, with nothing but good intentions, could end up building a powerful tool for the wicked.
