A nice idea, and must have been pretty simple and intutive for them to implement having made Stumbleupon. But Stumblevideo is a website in itself which gathers videos from google/youtube etc and plays it in a flash player. Tags are a plus. I was going through some computers tagged videos and see what I got. Microsoft has really done its voice recognition well. Hilarious!!! Just like the Windows 98 crash few years back.
