Saw this term on Business Blog Summit. It’s the perfect way to explain why blogs are so powerful as a means of communicating ideas. And why a blog can establish an intelligent writer as a “thought leader.” (Also, why blogs are much more powerful than discussion boards or regular old Web sites. A blog, by definition, is a form of viral marketing.) Byron, writing for Biz Blog Summit, puts it this way: “think of blogs as ‘topics, ideas, conversations, that grow like snowballs with each link.'”

To illustrate the snowball, here’s the reference back to Doc Searls’ (highly cogent, as always) definition of snowblogging.
