Strange Loop 2011, "We really don't know how to compute", Gerald Sussman (http://www.infoq.com/presentations/We-Really-Dont-Know-How-To-Compute http://www.infoq.com/presentations/We-Really-Dont-Know-How-T...). That's not entirely fair though, insofar as I'm a sucker for a Sussman talk. Beyond that, I'd have to say Sam Aaron's Overtone presentation @ Clojure Conj 2011. At the moment, it strikes me that the obvious common element of both talks and speakers are their absolutely infectious enthusiasm for their respective specialties.
