The opinion page in the WSJ is garbage, but otherwise it is a reliable source imo.
+1 to this. Many people get confused about the difference between opinion pieces on editorial pages and the actual news content.
Politico really rings as Center? I usually don't look, having thought they were left. I'll give them a little more attention.
I like the news.google.com feed for "current" news, but I always hit the "see realtime coverage" button to expand the feeds and pick whichever sources I think will tend to be more reputable. Often, it's the wire services themselves, not the branded sites. (I.e., Reuters instead of a newspaper that will carry Reuters content.)
I also pay real money for The Economist; I read some of it online, some of it on the paper edition that shows up.
I also agree about On The Media and Real Time... A lot of good stuff in both, and while Bill Maher has a definite bias on each individual issue, he doesn't hide or dance around about it, so you know where he stands.
I'll throw Last Week Tonight in here, as well. More focused on comedy than Maher, but some interesting "investigative humor," especially in the weekly ending rant.
