I 'disable comments' for two reasons:

1) I think the video speaks for itself,

2) I do not see the value in someone commenting, "Keith rulz! and I agree with everything he says", and another person commenting "Olbermann the dork needs to take his Groucho Marx eyebrows and leave on a LONG vacation. He is the most pathetic figure on television. Oh...sorry Rosie...the second most pathetic figure".

YouTube does doesn't give enough space (500 characters) for intelligent comments or thoughtful dialogue.

I believe that we're in this mess because people think that by posting a comment on the internet somewhere, they're civic-minded and making a difference when, in fact, the only thing that makes a difference is commenting where people with power will hear you and fear your removing them from power: Through phone calls and snail mail to your elected officials and marching in the streets.
