Google keeps telling them not to worry about PageRank but SEOs don't hear or listen. They think SEO is all about PageRank, when you and I know it has very little to do with PageRank. Especially Toolbar PageRank which is a fictional character used by Google's marketing department.
Well, a DigitalPoint Forums thread and an old WebmasterWorld thread have SEOs saying they see a PageRank update in the Google Toolbar. I personally did not check, so I am not sure, nor do I really care, but I am here to report these discussions.
