The OP reads like another of DB's unintentional parodies.
For example, "Most of them are fairly straightforward news organizations with no overt political agenda, like NPR, various network news, CNN, and the New York Times." I almost spit my coffee when I read that. I guess these are the same people who view obama as a middle of the road moderate.
There's a reason that the network news, the non-Fox cable channels and the liberal news papers are losing consumers hand over fist. People are sick of their bias and now they have alternatives.
And once again you confirm the thesis of the OP.
Thanks.
