Who said the new Yahoo PFI will get a site ranking higher? Why would the searcher need to be notified? Tim spelt out clearly in message 1 what the paid service involves...nothing there about being ranked higher or listed seperatly.
From what I understand, if there are good links to the site, you will be in the index (Yahoo's webamster guidelines say that) and I assume that most of us will not need the Yahoo paid service. (same as the Ink paid service - nothing to do with rankings, just a gaurantee you get crawled every 48hrs - if you alrady rank well at Ink, why bother paying?)
