YouTube and Libraries

Can you see any features or components of the site that might be interesting if they were applied to library websites? This is a perplexing question as the immediate response is to say YES but then I began to wonder if libraries, businesses, advertisers etc. start infiltrating YouTube then won't the "younger" ones find some where else to go? So maybe to have an effect/presence on YouTube you have to do something quirky or radical or find a way to get a "library" message across in an amusing way. One way is to show how librarians are not like the "stereotypical" type many people think we are! Show some of the technologies libraries are utilising. 23 things is helping many librarians! 23 things rocks!
