Blog or not blog is not the real issue — it’s all about pages. Blogging software just happens to be a readily available content management tool that works fairly well from a linking perspective.

Content (pages) is what ultimately creates Google PageRank and provides places to create links to other pages. The more pages the better, and blogs happen to be pretty decent at creating pages from content. The Mastering PageRank video shows a diagram of why that is.

There are examples of folks making money online with nothing but blogs — just as there are examples of folks making money online completely without the use of blogs. Success is about pages plus linking.
