My Youtube user name is 'RobPVLD', the video I watched is from Hillsong Church - 'Mighty to Save', great song. See link below.
I think Youtube is popular because anyone can upload their camera phone video's and any home video's for their friends, and the world to see.
The Library District could video tape 'Story Time', so that the Peninsula Parents could watch from the comfort of home. I know the Young Reader Librarian's would love this.
