Those of you who watch Google closely might be interested to learn about a new page on the Google Press Center site, titled: Google Podium. It provides access to transcripts (and in some cases video or audio) of speeches and presentations by Google executives. Of course, not each and every presentation by top Googler's are available but this page might be a good place to begin when looking for this type of material.
When I checked the page the other day I found Larry Page's CES presentation, a few items from the Google Zeitgeist conference, links to interviews with Sergey Brin and Omid Kordestani from Web 2.0, and a couple of other links.
An RSS feed is presently unavailable to learn when new items are added to the page but you could use a service like Web-Site Watcher, Trackle, WatchthatPage or something similar to be alerted to changes on the page.
