Google has updated their backlinks and has also began updating the PR bar. You need to download the Google toolbar (FireFox users click here) to see any site’s PR (PageRank).
We don’t pay much attention to it but still summarily rejoice when our PR increases. Its kind of a status thing in the SEO community.
