Tribler: A Next Generation Bittorrent Client?

The latest version of the “social” BitTorrent client Tribler integrates BitTorrent with YouTube while offering the best of both worlds: ease of use, browsing with thumbnails, HDTV quality, and Video on Demand support. The client uses an Amazon.com-like recommendation system to suggest what you might enjoy.

Some of the features of Tribler which set it apart from other BitTorrent clients are:
# Easy downloading: Moves P2P beyond keyword search, YouTube grid of thumbnails
# Recommendation and Friends: See what other people like, related files, find person with the same taste
# Video on Demand: When the download is on its way, you can use the integrated video player to start watching ASAP
# Wealth of content: Search both BitTorrent, Youtube, and Liveleak for content
