Well, Jill's forum gets an other plug here at the Search Engine Roundtable for the post titled Self-appointed Seo Expert Has An Opinion.
Dan Thies wrote a 17 page paper he names "Special Report: How To Prosper With The New Google", this document can be downloaded as a PDF (100k).
He reviews what the Florida update was all about. He then goes into shooting down most of the crazy theories about this Google update. And then presents his own theory on Google using a new PageRank algorithm that is based on not only the number of high ranking incoming links to a site and also not just about the anchor text of those links BUT now it also includes the type of site that links to you. If that site is part of your site's theme, then its worth more then a link from a site that has nothing to do with your site.
I find this theory interesting since this is what Teoma has developed a few years ago with its "Subject Specific Popularity". I wrote an article on this that can be read at Teoma - The Superior Search Engine?.
The forums and threads that are currently discussing this theory are at: Self-appointed Seo Expert Has An Opinion - HighRankings How To Propser in the New Google - Cre8asite Forums Dan Thies's Google Theory - SEO Chat Forums
