You have to wonder if this tag won't attract a lot more spammers and wannabes than real authorities. Not long ago there was a thread here on WebmasterWorld about a scheme for half-a-dozen different writers to all use the same author tag. I really don't see how it can ever be a reliable ranking factor, especially since some articles will have the tag and some won't.. In any case, it seems to me that an article should be ranked on its intrinsic value and quality, rather than the supposed "reputation" of its author.
