Nate used to be a 2p2er. 538 is a special blog inasmuch as it provides something that has never existed before. They give the most statistically sound analysis of politics. They don't really say much about policy, but looking a the politics of the matter and how it affects other politics of the matter. They're basically like a super duper pollster

I tend to only read 538 during election time, though

I spend the vast majority of my time reading commentary on journo, not journo itself. I've found that I'm great at filtering things well when I do that. Over the years I've found that Cenk Uygur is an awesome source for commentary (much better than I would have hoped for, honestly), and he puts out a ton of info so I tend to not spend much time on other sources.

For econ, I like Robert Reich, Paul Krugman, and Richard Wolff blogs. Reich is baller for anything related to econ in popular media, Krugman usually hits on key points from deeper in the econ/business field, and Wolff spends a lot of time on econ philosophy through a socialist lens

For other political issues, names I like are Matt Taibbi, Glenn Greenwald, David Sirota, Ezra Klein. There is a toonnnn of info on the net though. I'm subbed or marked to a lot of stuff I never look at, yet is generally great sourcing
