I know good general programming blogs (e.g. coding horrors;)). But I want a very nice specific XNA blog. Suggestions?
Shawn Hargreaves and Nick Gravelin are the two names that I often look for when searching for information about XNA.
This is not so much a blog, but Ziggyware also contains a lot of great information.
And you can also find useful information directly on the XNA Forums and GameDev.net Forums .
Oh, I also like reading Gamasutra , which has articles from people developing XNA.
I really like the Shawn Hargreaves blog . It has many code examples and shows many best practices and tricks to help development.
You can start at www.creatorsclubonline.com, they have a huge list of links to special XNA blogs. (not sure if you are looking at beginner or advanced level)
Meanwhile, here are some ...

it's better
It depends on what you expect from the blog. If you are looking for knowledge and methods, you would not waste time on Rimer's textbooks !
