Blog by Hugh Hewitt is an informed, educational, and compelling take on the new prominence of blogs and social media in today's business and politics. Hewitt clearly knows what he's talking about, and he does a remarkable job of weaving together personal experience, real-world examples, and a little bit of extrapolation to make a strong case for everyone to start a blog, and start one now.
That said...Hewitt is also a self-satisfied Neocon (I want to say "blowhard") who takes time to crow about the role he played in bringing down Kerry and assuring Bush's victory in 2004. Most of his "real-world" examples are of that sort. There is certainly valuable information in this book even for people who vehemently disagree with his morals or politics, but he doesn't do anything to help you overlook his bias. If you couldn't stomach reading a book by Rush Limbaugh (even one with good information in it), you should probably give this one a miss, too.
