Whew. Content from IdeaFestival 2009 is located in the IF09 category on the blog, the Flickr pool (as always, check Geoff Oliver Bugbee's work) and from the IdeaFestival on Twitter (please follow) and #IF09.
Numerous videos shot by Vest Adverting (thanks Susan and Matt!) may also be found on its channel.
