On looking around the YouTube home page I saw the tab categories, http://youtube.com/categories , so went there first to have a look at what was available. I chose the category Pets and Animals, and from there a video clip from National Geographic called Flamingos of Bogoria (duration 3 min., 14 sec) which certainly demonstrates there is no sentiment in Mother Nature. There were also homemade video clips on the site which people had made of their pets, some of which were very funny.
The first thing I noticed was the length of time it took to bring up a category once you clicked on it - bandwidth hogs indeed! However it seems to be a site of endless possibilities, and could keep anyone entertained for hours. Suitable video clips would be a great feature on library websites, drawing customers attention to events, services and resources.
