It doesn’t really make any difference to a site’s performance in Google anymore, but it still feels good when your site gets the little green bar. It seems like Google have just run the latest update of their page rankings. This blog, and my main Peter Anderson site, have both gained some page rank, and all my other sites have either gained 1 or stayed the same 
If anyone wants to read about the Google Page Rank you can here.
