I would like to nominate a Scott Hanselman keynote (or conference talk) as an example of one such talk. I think he blends humor well with information dense presentations.
Mike Monteiro was good (but I haven't heard much from him, lately). He seems to channel "The Angry Designer." I enjoyed his "F**k You, Pay Me" talk[0].
