I'm not sure YellowPages.com or Hoovers or any of the various data aggregators would agree that directories are an anachronism.

I don't consider either YellowPages.com or Hoover's "web directories." You could be in either of those and not even have a website. They are searchable business databases. I think a web directory is commonly thought of as a list of websites listed by categories. And I don't think Google qualifies (except where it uses the ODP).
