Another post from Matt Cutts. The best so far http://www.mattcutts.com/blog/more-info-on-pagerank/ Some questions: Will this PR update affect SERPs? Is this PageRank from day X or day Y? And it looks like backlinks are from day Z? Matt, I often wonder, how is the PageRank value stored internally, is it a floating-point number ?
