I noticed that google rolled out an update for their pageranks today. The pagerank you see from google toolbar, or pagerank status (firefox extension) are only updated around every two months.
Google does this to keep people guessing. If you could see your pagerank change every day or two, you would be able to figure SEO's would be able to figure out what works better easier.
