Oh, YouTube. What can I say that hasn't already been said? You've given the world a way to share their home videos, which leads to far too many "OMG look at the baby/cat/dog" videos that only a select few would want to see. You've given an outlet to crazy people (like the Russian guy that burned a copy of Harry Potter & the Deathly Hallows). And you've brought the art of bootlegging to a whole new level - now all the sneak previews that you can only see in theaters are snuck online by clever fans, and by the time the owning company can get it yanked down, enough copies have been saved elsewhere. And, of course, the world of fanvidding (creating music videos for your favorite tv show) has gone to a whole new level of sharing now that this site allows free uploads.
YouTube is a weird creature. My least favorite thing about the site is the search engine. I usually use Google to find things on YouTube because the in site search never gives me quite what I want.
It's funny watching the corporations try to figure out how to handle YouTube. It's free advertising! But...it's their property. But, they were running it on TV and so it was obtained freely in the first place, why is it different if I'm watching it on YouTube? (This has been the big debate when Viacom said that no Comedy Central clips (specifically targeting 'Daily Show' and 'Colbert Report') could be uploaded on YouTube. Even Jon Stewart has mocked this decision.)
I think YouTube is something programmers should take advantage of! Think of the fun teen contests we could have! Make a commercials for your library! Interview a librarian and post the results! Make a music video about your library! Of course - you have to be of a certain age and class level to afford the video & computer technology for these sorts of things to work. Unless of course you have the kids submits scripts...and the winning script the library could film with their digital camera....hm....a plan is forming....
Okay, I'm going to go find a few videos to post. I have a couple in mind already that I want to share.
