I've seen two inaugural poets in my lifetime--studied under one at the University of Arkansas--so it's not like George W. Bush deciding not to have one was a huge break from tradition, but I am glad to see that the Inaugural Committee is bringing it back for this one.
The poet is Elizabeth Alexander, about whose work I know absolutely nothing. I'm sure I'll get a taste of it between now and January 20th. According to her bio, she's of the same generation as Barack Obama, studied with Derek Walcott at Boston University, and was a finalist for the Pulitzer in 2005. There are links to three of her poems on the same page as her bio.
