I'm not terribly impressed, but more online streaming TV is cool.
Unlike Youtube, JumpTV.com is a site with streaming television channels, not uploaded videos.
JumpTV is great for those not in the U.S., and good for those interested in the World Cup. There were only two channels out of the United States, and unless you were told they were American channels, you wouldn't think so.
But hey, free online TV is always cool, plus I got to see a base jumper jump from the tallest building and the perform the shortest jump from Christ's hand.
