Thanks for the youtube tip... that will definitely come in handy!

Oh and there is no sign-up directly on the comments section... I had to go to the Intense Debate site manually to sign up.

Intense Debate looks great, but I have a couple of gripes... 1) The thumbs up button is on the left, which is opposite of the way it is on digg.com... I just accidentally hit thumbs down on a comment because of that. 2) They don't have a version of the .js file hosted on HTTPS... that means I can't use it on a secure site I'm designing at work because in IE users will get a "This site has both secure and non-secure items" alert each time they change pages, which is extremely annoying and can cause users to think the site isn't secure.
