Eric Nolin, who helped organize and build Digital Identity World with Phil Becker is starting a new conference with Phil and Brad Feld (of Mobius VC) called "Defrag." From the "About" page:

Defrag is the first conference focused solely on the internet-based tools that transform loads of information into layers of knowledge, and accelerate the "aha" moment. Defrag is about the space that lives in between knowledge management, "social" networking, collaboration and business intelligence. Defrag is not a version number. Rather it's a gathering place for the growing community of implementers, users, builders and thinkers that are working on the next wave of software innovation.

IT Conversations is one of the media partners for Defrag and will host the audio from the event after it occurs (Nov 5-6) in Denver. Leading up to the event, we'll also be doing some pre-conference interviews with some of the keynoters and other interesting people.

I don't know Brad, but Phil and Eric know how to put together interesting, useful conferences. I'm excited about this one. For updates, follow the Defrag blog.
