Also note how Google seems to love the blog format (even if a lot of web surfers don't). They have all sorts of services for blog authors. I think blogs are very useful to Google. You have 20 blog posts, across 20 blogs, on "Topic X", each linking to a new web site featuring more information on "Topic X". It gives Google a good context when it needs to index that site so as long as the linking looks natural (not artificially setup by spammers.) And if I'm a decent writer I am naturally introducing many more related keywords to the context, and links referencing external sources, just by writing about Topic X. Google no doubt is designed to recognize natural language, it should be the holy grail of language parsing.
