KeenTalks is a Curated Collection of Talks and Lectures on YouTube

If you enjoy the presentations on TED Talks you may also enjoy Keen Talks, a webapp that takes thousands of lectures, presentations, and debates on various topics sorted for easy browsing and without many of the distractions normally found on YouTube. The webapp sports a clean design with one panel of advertisements on the side.
