Nielsen basically posits that 90% of the people who visit a social or community forum are lurkers, people who read what you've written, but never quite get sufficiently motivated to contribute a note, comment or email message. The remaining 10% are the contributors to your blog or discussion forum, and that further breaks down into 9% who are occasional contributors and 1% who are frequently contributors and typically account for the vast majority of your comments.
Specific to blogs, he suggests that the rule is better described as 95-5-0.1.
