Good Economic sites:

http://nakedcapitalism.com (Yves Smith - an alias)
- A lot of insight into the complexities of finance/banking.

http://calculatedriskblog.com
- pretty cut and dry, but still very informative.

http://delong.typepad.com/sdj/ - Brad Delong
- at times a bit abrasive (usually in a good way), but still quite knowledgable.

http://krugman.blogs.nytimes.com/ - Paul Krugman (you may have seen him on TV)
- Similar to Brad Delong, and very good about macroeconomic policy (even if you disagree with his treatment (which I kind of do), his diagnosis is often very good.

http://globaleconomicanalysis.blogspot.com/ - Mike Shedlock (Mish)
- Has a different perspective, and is seemingly less convinced that fiscal/monetary policy can stave of deflation/depression.

http://theoildrum.com - a very different perspective, but still worth while. Although right now demand is low enough where in the short term energy isn't the problem it was.

There are a lot of others too, but those are the main ones. A lot of economic commentators are one trick ponies (they look and something and decide _that's_ the problem) - the best example are goldbugs.
