The news broke today CBS has named Stephen Colbert to replace David Letterman when Letterman retires next year.Reading a lot of positive reaction to the announcement. Colbert says he won't be in character like he is on his own show now. I don't watch his Colbert Report show, but I've seen him with Jimmy Fallon and I watched this brilliant commencement address a few years ago at his alma mater, Northwestern University. I think he'll be okay.
