Fableweak should take note of the follwing example of how an author and journalist admits to an error. The entire corespondence is docuemnted. All relevant commentary is noted and corrected. The publisher (of the book) is asked to remove the incorrect statement. The error is clearly admitted with a clear explanation of how the error arose and why it was wrong. Compare with the semi-retraction, super-retraction etc. etc. of Fableweak or for that matter of CBS.
Update: Various commenters are stating that because Michelle took 9 months to respond to that particular retraction it is not really comparable. I disagree. If you have looked at Michelle's Erratum page over the year or so that the book has been out it has had corrections added as and when noted and that the page is clearly identified as the place to go. Had this particular error attracted more attention than it did I have no doubt that the process to correction would have been faster.
