CNET.com has, they say in an email, decided to turn off Newsburst, their attempt at a feed reader page.
Here's the text of the email.
Dear Newsburst user,
We're writing to let you know that as of December, 31 2007, we
will be shutting down Newsburst, CNET's Web-based feed reader.
We will provide a link to export your feed sources so that
you can import your feeds into another Web-based or desktop RSS
Just log in to Newsburst and look for the 'Download OPML' link at
the top of the page.
