This is from back in Jan, 2011. As in, last year. But I suppose one would never know.

Title is misleading. How much of the rest of the story is exaggerated?

Okay, you've convinced me. It was the lack of privacy that gave me pause. And the well executed Nook.

And that's the reason that the redirect in the article includes "301" -- to indicate to the search engine that it's a permanent redirect.

Good info there. Should note that the article is agnostic about which is better (with or without www). It tells how to make it work with both versions of the domain, and then suggests redirecting to one of those domains to focus link juice.

Also note that in our experience, Google Chrome does not redirect automatically to www. And Chrome is very, very popular now.

Chrome doesn't do that exactly, it requires Control-Enter (which I admit many people wouldn't try). The autocomplete/search during typing does tend to product correct domain suggestions too.
