The "This Week in Law" Program is one of the TWiT family of shows.
In Episode 14 "Blogger and Podcaster Liability" Denise and her panel of guests talk about law, risk, insurance, defamation, anonymity, "broadcasts", corporate blogging, forums, blogging policy, and more.
This episode is chock-full of information of interest to "anyone who has hosted an online conversation." That's my term for blogger, podcaster, lifestreamer, moderator, online community manager, etc. Many legal issues remain unresolved, and will find resolution every time a landmark case gets decided.
Blogging isn't going away, so it's important to familiarize oneself with the legal issues. This program does not overuse "legalese," but will help you learn terms of art such as "expectation of privacy."
One interesting issue discussed is the emergence of blogging lawyers, one in particular who was "recruited away" and caused his old law firm to embrace blogging in the interests of remaining competitive.
