Public Citizen's guide for citizen-bloggers

Public Citizen explains the guide as follows:

This is a guide for bloggers and non-profit organizations about writing with libel considerations in mind. The guide discusses the elementary principles of libel law and explains how to prepare for and conduct a pre-publication libel review. It is particularly importance to have a third party, not otherwise involved in the preparation of a report or blog post that criticizes individuals or organizations, compare all possibly-defamatory statements with the sources for those statements.

It should prove very useful to citizen journalists.
