Where Did My Google Page Rank Go?

With the latest round of page rank updates it appears this blog has suffered quite badly. A few weeks ago it had a page rank of 3 before dropping to a 2 and yesterday it dropped from a 2 to a 0. I don’t pretend to understand how Google work out page rank but the change in rank is certainly nothing to do with the amount the traffic the website generates. If anything this blog generates more traffic now, than when it was PR3.
