As Tom says above, he's in Sydney doing another one of the Leaders events. The date of his appearance is 26 October, but it is the 26th there already, so the slides are available here now. There's also a longer Web-only version.
Before blogging became all the rage, Tom was posting book reviews and Observations (essentially early blog posts) to this site. You can find the archives below.
