One thing about podcasting, there is a fine line between opinion and libel. How you say something about someone can have very significant consequences. Some Podcasters think that their microphone is going to protect them from a libel suit.
In my book on podcasting I spent some time talking about the ways one can usually keep him or herself out of trouble. But recently I have been listening to a particular podcast that was brought to my attention that could land that podcaster in the middle of a libel suit.
Podcasters would be wise to spend a little time looking over some basic Journalism rules and learn that their actions and commentary could land them in a court of law and cost them a pile of money to defend those words.
