I listen to NPR pretty much all day during the workweek.
Talk of the Nation airs in the afternoon, and the host, Neal Conan, fields "tweets" from Twitter. Seriously, how self-important have we become that we think someone else cares about "What are you doing?", but after reading about Christopher Walken's Twitter page on another blog, checked it out and joined.
Just what I need. Something else to waste more time with on the computer.
