You Tube

First I searched for library videos from my home state of Minnesota and found a rather cute video from the Eden Prarie Library about common misconceptions about their library. Best of all it's hosted by a teenager, so maybe it will reach some of his contemporaries. You can find the video at http://www.youtube.com/watch?v=mi78YJ1CD4Y.
There were 1,980 returns for my favorite dog, the Shetland Sheepdog, and if you'd like to fall in love with this breed, take a look at http://www.youtube.com/watch?v=me46O63yT0g.
The features I most like about You Tube are the different ways to sort returns, that's it's democratic in the sense anyone can participate, that you can see videos from around the world, that tagging is allowed, that viewers can rate the videos, and that there's a huge variety of contributors from a young kid to the Associated Press. I like that the possible postings are almost endless - I even found the recent Wimbleton.
YouTube features could probably benefit a library in a number of ways. Most obviously, a video could provide publicity for the library and you could could continually update what's new at the library. Book talks could be placed on a site like YouTube. Perhaps some of the best programs outside speakers and staff have done could be archived on YouTube.
Drawbacks would include the same democratic nature that I sited as a positive, in that there are many videos not worth watching because of the content or the poor quality of the videography.
The sheer size could be considered a drawback, too, in that there is so much available to wade through. One drawback that they've already experienced are people posting malicious pranks that are then copycatted.
