It could simply be that Google is fine tuning its algorithm, besides Google have always stated not to worry too much about PR, but to concentrate on building quality content, and solid backlinks and the PR will follow
Google says a lot of things my friend. Head over to the marketplace section and you'll see how many people are seeking out high PR pages/websites
These dates, Google is updating their page rank quite frequently. Not like last year, where webmasters had to wait 8 months
Yes, it is a major PR update. Some of sites that were made as recent as 18th July acquired PR. I wonder if this means that PR will be updated much more frequently from now on. Â
Lolz, I think that Google is playing with PageRank algorithm. Every week we all shocked with new PR update. I think they are doing PageRank update today. Lets see whos got PR and who loose PR
Yes friend. Yesterday Google has update the PageRank and i think its rolling out today also, But these update will effects your websites inner pages and sub pages. my most of the inner or internal pages of blog have  got PR-2 to PR-3 but didnt effect my Index or Main page rank. I am really happy
Yes google has updated PR this month ... last month google has Update 3 times .. many of my web is down and up ... heheh ....!?!..
