Why Can't They All Be Videos?

I have to say, I thoroughly enjoyed watching the TEDtalk in addition to reading the usual scholarly articles this week.  Points to Dr. Yang for including such current and multimedia information sources among our course readings.  Speed of delivery and the lessening demand for concentration make videos or podcasts and instant favorite among my methods of information consumption.  Wouldn't it be great if more libraries used these types of presentations for promotional purposes?  I'd listen to a library podcast (drop a note if you know of one).
