I've become addicted to getting news through Calibre (on my nook). So far, most of the newspapers, blogs, etc. read very well on the nook. They seem just as easy to navigate as the few newspapers or magazines I bought for it. The paid newspapers and magazines do have more content, but I figure I never have time to read it all anyway. (I'm still tempted with a few of the paid ones now and then, and my tacky side wants to see New York Post available for the nook.
)
It hasn't been perfect. It turns out that Dilbert is a little hard to read on the nook.
Also, a few sites took too long to upload, so I removed them.
