Being in Aus we don't get to see many live and rely on the videos being made available. Of those I particularly liked Daniel Spiewak's "Extreme Cleverness: Functional Data Structures" and Rich Hickey's "Simple Made Easy".
We were fortunate enough though to have the excellent YOW conference with many excellent talks, particular stand-outs coming from Simon Peyton-Jones and Mike Lee, but the absolute best talk (not necessarily the best tech, it is Perl after all) was Damian Conway's flabbergasting "Temporally Quaquaversal Virtual Nanomachine Programming In Multiple Topologically Connected Quantum-Relativistic Parallel Timespaces...Made Easy!"[1]
