I saw this video over on Debbie Weil's blog, and it apparently aired a couple weeks back on MSNBC. They do a pretty good job highlighting the value of a "blogger-in-chief".
I like that Bill Marriot handwrites his blog posts -- there's something nostalgic about that in a technology-driven world. But at the same time, that can be limiting. Relying on an extremely busy CEO, and someone to transcribe his notes, is a bit tedious.
Free up the employees to create content. They're communicating everyday with potential customers on phone and email, why not a blog?
