Wow! It looks like Google is updating pageranks now.

It seems is now in the process of updating publically available pageranks.
As usually, the update can take up to several weeks, so we can see some "jumps" of page rank values up and down, and different pagerank values are sometimes shown by google toolbar and by other page ranking tools during the update.
It looks like many web sites are going to get quite good page rankings this update, and wishes you to get the highest ranks for all your web pages.
