There is nothing more informative than a podcaster.
You certainly have to use your discernment re: podcasts to sort out the chaff, but to dismiss all podcasts as junk would be foolish IMO.
This is the new world we live in. People like you and me and other Freepers have opinions that are as valid as those of MSNBC and CNN. And those opinions can reach millions of people.
And for what it's worth, I learn more from Freepers than I ever learned from the mainstream media.
