Daniel wrote a post detailing the speakers for the upcoming SIGIR 2009 Industry Day he's organizing.
It's an impressive lineup including Matt Cutts from Google. Given Daniel's experience at Endeca, it should be no surprise that Enterprise Search is a main theme, with two panels. The first panel is of leading vendor technologists and the second is for industry analysts.
The great news is that the track is free for those attending the main SIGIR conference.
