Seems google have a web site for almost everything these days. Well if you've missed it Google has a video site that 'offers viewers a way to see material from archived TV programs, educational videos, personal productions and more'. There is also the ability to upload your own videos. In terms of sorting through the videos Google offer an official Google Video Blog.
But my favorite is the unofficial 'Google Video of the Day'. This site goes through the videos and then posts one per day deemed to be of most interest. See amongst many other things clips of an octopus devouring a shark, a redneck rollercoaster, a crying Darth Vader eating pie.
