Stars have recently appeared next to some of the threads in this forum, but there's no key to how the ratings have been compiled, why, or by whom. I can't make sense of them on a merit basis--the spam thread ("Freelancers") gets a star, while worthy threads lack any.
On a related topic, I recently learned that Amazon.com includes ratings from other editions of a book, even if the text has been substantially revised. For example, the reader reviews of the 2nd edition of Morgenstern's "Organizing from the Inside Out" include reviews of the first edition, despite the fact that the second edition is over 70 pages longer. Amazon justifies this because "the titles are the same." Caveat emptor.
Back to GTD, can someone please explain the stars?
