Last Google Toolbar PageRank Update of 2008

Matt Cutts has confirmed that Google has again updated the PageRank displayed on the Google Toolbar. Looking at my blogs it seems to be effective approximately Dec 16th. I have some blog posts from the 15th and before with pagerank. On the 16th I have one post with a pagerank and several without. On the 17th none of my posts have pagerank. This means while the pagerank was displayed today, the data used is from about December 16th, I believe.

The displayed pagerank is more fun than a measure that can be relied on. But I still find it fun to look at the pagerank values - except when they go down for my sites :-(

Check the current pagerank on your sites using our related site: Multiple Site PageRank checker. Updates from our Google PageRank Update, July 2008:

Curious Cat Investing and Economics Blog - 4 (July 2008), 4 (December 2008)
Curious Cat Engineering and Science Blog - 5, 5 - 3, 3 - internship directory - 4, 4
Statistics for Experimenters - 3, 4
CSS 4 Free - 4, 5
Wordpress Themes for Free (new site from November) already a 3 Google pagerank.
Curious Cat Management Improvement Connections (one of my most popular pages since 1997) - 3, 3
Multi Site PageRank Checker - 1, 3
John Hunter 4, 4
Life and Legacy of William Hunter (my father) ?, 4
Justin Hunter (my brother) ?, 2
Curious Cat Articles and Links (this blog) - 3, 3
Curious Cat Management Improvement (v.1) I started the blog on blogger and then moved it to my own domain using WordPress in 2006, still it retains a pagerank of 3
My Kiva page ?, 3
Reddit management (new in September) 0
Curious Cat Web Directory 3, 4
Rocky Mountain National Park photos ?, 2
Boston Museum of the Fine Arts, Glacier National Park Photos, Parfrey's Glen, Wisconsin Photos, The Cloisters Museum and the Museum of Modern Art, Shaker Village of Pleasant Hill, Kentucky ? , 0 ( much of the Curious Cat Travels seems to be without pageranks - which seems odd to me but...)

The Curious Cat Engineering and Science Blog has actually been a pagerank 6 before, but I think it is a high 5 (of course I may be biased and that is just wishful thinking). Many brand new posts for example have ranks of 4, likely because they were on the home page when the snapshot was taken - Bird Brain, Passion for Mechanical Engineering, High School Inventor Teams @ MIT...). Another thing this means is those pages are really not pagerank 4 even today. The toolbar snapshot from Dec 16th shows them that way but only because that was the value on Dec 16th.

Now, I would guess they are probably really pagerank 2 or so. If I just look back at say random posts in August 2008 (or really any month) they will be between 0 and 3. I really don't understand the differences between say 0 and 2. While there is some difference, most of those pages have 0 links from external sites. And then I will have a small number of posts that get significant external links that maybe be 3,4 and even 5 pageranks: The Engineer That Made Your Cat a Photographer, Sep 2007, pr 3, Best Research University Rankings, Sep 2008, pr 4; Economic Strength Through Technology Leadership, Jul 2007, pr 4

In my experience it is often more telling how the pagerank of internal pages. I find it that there are many sites with say a pagerank of 3 or 4, or even 5, on the home page but almost no pagerank on internal pages. While other sites with a pagerank of 3 or 4 have many internal pages with pagranks of 1, 2, 3 and 4,
