Part of the problem with calculating expert/authority sites is if the data set is filled sites that are there for the sole purpose of manipulating the data set itself. Is my widget site really that much better than yours? Maybe I can convince you it is, with enough critical mass. By throwing a date factor in they can combat hit-and-run SEO and grow the web up a little.
