The purpose of this Guide is to provide you with a general roadmap of some of the legal issues specific to podcasting. EFF has produced a very practical and helpful guide for issues related to blogging generally. This Guide is not intended to duplicate efforts by EFF, and in many cases refers you to that guide for where crossover issues are addressed. Our goal is to complement EFF's Bloggers FAQ and address some of the standalone issues that are of primary relevance to podcasters, as opposed to bloggers.
