An excellent social video browser
Shufflr is a video browser with highly integrated social features, allowing you to share what you're watching, find like-minded people, and get personalized recommendations. Running through Adobe Air, Shufflr has a slick and elegant full-screen interface. It collects all the major video portals like YouTube and Metacafe, allowing you to search, play, browse, and share videos with Shufflr friends as well as through Facebook (and soon Twitter).
The social network aspect of Shufflr enables you to quickly build a community of like-minded viewers, from whom you'll receive automatic recommendations based on your tastes. Shufflr's black interface looks great when viewing videos, and the browsing experience is quite dramatic as you drag a wall of videos around in 3D!
Shufflr is still building its community, but as you're able to share through Facebook with it, you won't feel lonely. The only drawbacks are that there seems to be no windowed mode to Shufflr, and older machines may struggle with the Adobe Air interface, as it can be a little resource heavy. Overall, Shufflr is a great-looking video browser with excellent social integration. Watching and sharing videos has never looked so good.
