Norman Yarvin's contribution is to pull these good articles out of years of discussions which he followed, usually taking them out of threads with many comments and varying subjects, and to present them sorted by subject matter. It would take a huge amount of effort to duplicate that. Sure, you could find these articles with a search on some archive, but they would be found among thousands of hits of, putting it very mildly, rather lower value. Yarchive is a very valuable site.
