This is really great what's happening these days on the net. I've watched prior POP Tech conferences from IT Conversations extensive archives. This years conference starts the 19th and will be broadcast live, thanks to yahoo.
Themes this year:
Participation - Democratization - Open Innovation
Here's the link to their blog.
"Every October, five hundred of the world's most provocative thinkers gather at Pop!Tech (www.poptech.org) for three days of visionary conversations about science, technology and the future of ideas. It's a conference experience like no other - but one that has been limited to the relative few who get to participate in-person."
