It's true, Scavhunt does have a tendency to (mis)appropriate internet phenomena, and frequently does so on their own turf. When Slashdot appeared, Scavhunt got Slashdotted; when Google took over the world, we tried to get Scavhunt onto the Google homepage. When Facebook.com was all the rage in social networking, we gave the world Assbook.net for a few months.
These days videoblogging is suddenly big, thanks to services like YouTube taking most of the hosting complications out of the picture. And Scavhunt is there, too. Check it out -- Scavhunt in motion!
I especially recommend my team's documentary on liquid nitrogen.
