I'd watched videos on YouTube before, so this wasn't completely new to me. Once I had ordered my quilting machine I searched for videos on machine quilting, lining up pantographs, loading the quilts, etc. And heaven knows I've watched the kids watching funny cat videos at the library. So, I decided to go one better than our exercises instruct. I uploaded a video my granddaughter took with my digital camera at Christmas and this is it: That's my daughter & grand-daughter playing their new Wii at our house on Christmas Day.
A library could use YouTube to publish a promotional video. Or, maybe video some library activity so the kids & their parents could see themselves in a video. Could video a presentation or how-to video (like using the microfilm reader or something like that) and patrons could watch it. YouTube could be a useful tool but there's also an awful lot of crap on it that it would be just as well without. I guess the same applies here as anywhere...be selective.
