"AuthorRank, of course, wouldn’t be a replacement for PageRank, but would be used to inform PageRank, therefore enabling Google to rank high-quality content more appropriately. I think AJ’s right on the money and that it’s not a matter of if Google rolls out AuthorRank, but when.
I’m certain that Google is going to begin incorporating AuthorRank into their ranking algorithm in the not-too-distant future. I’d put good money on it. All the signs point to it: Google’s emphasis on social, Google Authorship, their ongoing efforts to measure site trust, and their progressive devaluation of raw links as a ranking factor. People want to read content written by credible and knowledgeable people and using AuthorRank as a major part of their search algorithm just makes sense".
