One of the blogs that I read regularly is John Chow dot Com, which mainly focuses on how to make money online. 

John's blog is one of the best in a seemlingly endless line of blogs writing about blogs, and how to monetize them.  I think it's very tough for others to break into this very competitive arena but what I get out of the blog (and what most business owners can get) are good ideas to generate traffic to your blog/website. 

If you want to review his blog, he'll link to your blog from his site.
