Google updated the toolbar PageRank over the weekend and already several webmasters, seo's and conspiracy theorists are pulling out their hair trying to make sense of it all.

Page Rank updates have a habit of getting everyone riled up and upset, but when you begin to understand the calculation, the method and the relationships between PR and SERPS, or lack thereof, you'll feel a little smarter, depending on whether you took a hit or not.
