U Tube

There is so much on the news about U Tube, good and bad. Millions of people use it, watch it or hear about what's on it. I personally have never looked at it prior to this. I was thinking what the library could do to utilize some free advertisement. Maybe some skits or small clips of upcoming events that people might be interested in. Also I was thinking about the self checkout stations. How about a video showing patrons how to use it? But then I thought, if someone knows enough to use the computer to go on U Tube, they're probably not the patron who would have a problem using self check out. So that idea is out the window. I did review a self checkout on U Tube. It was self check out at Walmart. Where else?
