One of the points I will be making at the Hasbara 2.0 event I am giving tomorrow is that cameras are cheap, and YouTube is free. And if a terrific speech is made to a roomful of people, if it doesn't end up online, it might as well never have happened.
Maybe a thousand people were at the event. But in the couple of hours it took me to edit and upload the video, it is now available to millions. Pretty simple math, and great bang for the buck if you want to help defend Israel.
