Since I have been using Radian6 for Buzz Monitoring I've noticed more and more events where Radian6 has poped up, such a Twitter/Webinar on Social Media which Drew a Big Crowd today (I didn't know about it - it was written up in Social Media Today).
But I did go to an event tonight in Manhattan and taped much of it - it wasn't as detailed a presention as what I have been given personally, but I think it does a good job of showing you what people buy and use Radian6, and tools like it, for.
Enjoy, and let me know what you think.
