a YouTube for people who exercise their brains

Ideas, not dramatic chipmunks, are the stars at new video community site BigThink.com.

In order to get the conversation started, the site currently has several hundred short video interviews with well-known thinkers -- professors, CEOs, diplomats, politicians and  writers, such as former Dallas resident Virginia Postrel. Topics range from the meta (identity, death, justice, etc...) to the physical (culture, economics, technology). The interviews are there to start the debate. You can comment, respond, or post your own topic/question via video, slideshow, audio or text.

I found one question in particular, "Can newspapers survive the digital revolution?" to be particularly relevant.

Ready, set, think.
