Business Blogging vs. Corporate Blogging

While browsing through Google's search engine result pages (SERPs) to provide a to-the-point definition of "Corporate Blogs" for my thesis, I found that most sites seemed to be using Business Blogging and Corporate Blogging synonymously.
On the other hand, I had a really hard time finding a website that actually deals with the question of what business blogging is. Not even Wikipedia, who usually is ahead of everybody else when it comes to defining things, holds an entry. Instead most of the pages to be found when searching for business blogging talk about blogs set up by companies. Even with the definition I found in Mark White's "Glossary of Blogging" @betterbusinessblogging.com you could be led to assume corporate blogging and business blogging were pretty much the same, which is NOT the case.
Inspired by Debbie Weil's rather sketchy thoughts on business blogging in her "Corporate Blogging Book", I decided to phrase my own definition:

Business Blogging is a company's or an individual's activity of involving and utilising the blogosphere for business objectives and commercial success.

The definition implies what Debbie states in her book: Instead of being equal, Corporate Blogging is merely a small portion of Business Blogging. Business Blogging encompasses a lot more: A person living off their blog falls into that area. Marketing agencies that publish ads on public weblogs just the same. So do media companies publishing adsupported blog networks.
Business blogging is everything to do with the question: "How can we make money out of the blogging phenomenon?"
