In October 2009 the Harold Washington Library Centre in Chicago helped students with a podcast to the President. The students were invited to express via the podcast what they believe has changed or still needs to change in America. They used the thisibelieve.com website to post their podcast.
I think this is a very innovative program. While perhaps not everyone would find this appealing, it does give socially aware teens the opportunity to speak their mind and express their concerns. Giving a voice to youth is so incredibly important and I tip my hat to the Chicago library for initiating this.
