Ezra Klein, Matt Yglesias, Brendan Nyhan (not exactly liberal, but they should still read him), and you.
Jared Bernstein's On The Economy is good; Ta-Nehisi Coates at the Atlantic, Alyssa Rosenberg at American Progress (for pop culture). And all the above.
Harold Meyerson and Michael Lind.
Michelle Goldberg, Mike Konczal, Peter Frase.
I think the "plainly worth reading" list to the right is pretty good start I'd also through in some of the well known people like Paul Krugman. In terms of interesting bloggers that plain bloggers might not know about I would to point people to the British film maker Adam Curtis's blog. Curtis is well known in Britain but is almost totally unknown in America, indeed you can only get one of his movies on netflix as far I can tell, despite the fact his films are shown on the BBC and regularly attract millions of viewers. He's made a series of interesting and controversial documentary films over the years dealing with everything from the limits of technocratic rationalism in a series called Pandora's Box to the use of Freudian thought about the mind and how that shaped the rise modern mass consumerism in a four part series called The Century of the Self. Here's a blog post about the rise of modern think tanks http://www.bbc.co.uk/blogs/adamcurtis/2011/09/the_curse_of_tina.html which is quite typical of his work, that is it sounds incredibly boring but he makes it really interesting and uses a lot of found news footage to tell the story as well. He also deals quite a bit with middle eastern history, here's a great post about the rise of the Baath party in Syria and how it relates to the current crisis there http://www.bbc.co.uk/blogs/adamcurtis/2011/06/
Te-Nehisi Coates and Jeffrey Goldberg
It's weird to say that more people should be reading the blog of a NYT op ed columnist, but yes more people should read Krugman's blog (not just his column). He devotes a lot of time to debunking all of the bad economics our public discourse is drowning in and expanding on the case he makes in his columns for the need to do more to create jobs and grow the economy rather than do austerity. Matt Yglesias is also very good especially on the Federal Reserve. There are numerous other excellent writers out there in the liberal blogosphere of course, but those 2 would be my nominees given the overriding importance of economic issues right now.

For Boz -Angry Bear, Asymptosis, Ecological Headstand, Gin and Tacos, Reality Base Journal, Econospeak, Tim Duy's Fed Watch.JzB
He's not really liberal or conservative - one of the few who is genuinely a moderate - but Dave Schuler at The Glittering Eye deserves a much larger audience. The most rigorously fact-driven blogger around.One the pure liberal side, I'd recommend Lance Mannion, who is just a helluva writer.
Robert Reich should get more attention. Also Angry Bear (including especially postings on social security and econometric analyses by Mike Kimel over the years).

Andrew Sprung, xpostfactoid. yes he's on your list, but it sometimes seems that his only readers are his fellow bloggers. He's a wonderfully perceptive writer and thinker on most of the issues of the day, but especially on the nuances of rhetoric and persuasion.

None of them. People should read more expert reports, hard news (especially world news) and government documents and much, much less of bloggers, "analytical" reporters and columnists.
Oh, and books. If you must read political analysis, read books.
Corey Robin, for a good understanding of conservatism; Peter Frase, for his idiosyncratic view on whether or not work is desirable/necessary.
